Reviews
"Worked great for getting the nasty grunge out of the nose pads on my eyeglasses. We haven't used it on my wife's jewelry much because of the various recommendations out there about putting gemstones (and synthetic ones) into an ultrasonic cleaner. The glasses are 3 years old and had a couple of small, but obvious paint chips from wear and tear. Apparently there were a lot of very small rough spots in the paint after 3 years and the ultrasonics "cleaned them" off the glasses entirely."
"Using just soap and water to clean it did not make me feel confident that it was thoroughly clean, so I just pop it into the machine in the morning with water and a drop of dish soap, leave it on for about 4 minutes, and then I'm ready for the next night."
"I cleaned all my jewelry and glasses and the jewelry sparkles and the glasses are squeaky clean."
"I could see really tiny bubbles of air moving (vibrating) the sludge out of the dichroic reed tunnels, cleaning the inside of the to-be-fire-polished pieces."
"People LOVE receiving them because they aren't an item that they would ever think to get themselves."
"Tomorrow I'm going to clean my jewelry and my husband wants to clean his watch. I would definitely recommend this to anyone who wants clean eyeglasses and jewelry."
"I do not believe it is the right item to clean silver (as a previous reviewer tried to do) I would purchase one of the plates to use in hot water, I have found that's the easiest way to clean silver."

Reviews
"The first round I washed 4 rings, 2 bracelets, 2 necklaces and a watch band (I ran one cycle per each side of the watch as to not get the face wet.). I her wash her watch band an rings- you could literally see the dirt streaming off of the watch she wears for work."
"I threw in 2 platinum necklaces, my wedding ring and some miscellaneous Lia Sophia earrings (knowing full well there was the potential for damage to them based on reviews). I do love to give honest and true product reviews as I base a lot of my purchases on other peoples reviews."
"I was amazed the first time I used the Magnasonic Professional Ultarsonic Polishing machine because it was: a) so easy to use, b) so quick to clean, c) was able to use my own dishwashing liquid, and d) the results were as good as any professional cleaning I’ve ever had!! Utlrasonic Polishing machine is so easy and quick, you can clean your silver jewelry weekly, which leaves it bright and shining all the time."
"Don't be surprised it is smaller than you think but that is a good thing because you can dispose of the solution and use new all the time to keep all your jewelry clean."
"Bought this a while ago now and it is still working."
"I have used it nearly daily to clean all kinds of jewelry that I have collected over the years."
"I have really tried to give this little machine a chance, but I honestly do not see any sparkle in my diamonds after cleaning several times consecutively."

"I've previously bought a couple of the 5 pound bags and was kinda leery of buying this big of a bag because both my previous (smaller) bags came with cuts and spillage."
"I haven't opened the 10 lb bag of citric acid yet because the 5 lb bag I had isn't empty yet."

"I mainly use citric acid to clean my water well system and it works GREAT."

Reviews
"I would love to buy another one, but don't have the room. I purchased it to put our SPT countertop dishwasher on. If anyone knows of a smaller stainless steel cart (preferably with wheels) please let me know in the comments."
"NSF rated (A little taller than table or counter height--especially with he additional wheels."
"The table legs and shelf are packed inside the bottom of the top of the table, and the legs are individually wrapped. I received all parts necessary to assembling the table & even got an extra leg bracket (where the leg fits into the shelf)."
"Comparing the price of this to others I thought I would be getting what I paid for, but I couldn't justify spending the big $$ for a rolling table. This table came packed in a a nice box, all of the parts were in it and it is super simple to put together. The table top is a nice quality wood that is clear coated and smooth. The reason I bought this table was to use with my brand new UUNI Pro Pizza Oven. The UUNI has stainless steel legs that are somewhat slippery when sitting on top of this table. I stuck some rubber feet on the legs and it holds the oven in place perfectly. The wheels are a nice size and will roll over most stuff (concrete, decks, etc), but if you need to push it over grass they may be too small."
"We mounted the dishwasher on this cart, load the dishes in the kitchen, and the cart wheels easily into the bathroom where the dishes are washed."
"Great height for working while standing as well as while sitting on the adjustable stainless steel work stool that this company also offers."

Tekpower TP3005T Variable Linear DC Power Supply, 0 - 30V @ 0 - 5A with Alligator Cable and Power Cord, Upgraded TP3005D,HY3005, Mastech
Reviews
"I tested it with my Fluke 87V, and was very surprised to see that the reading on my meeter and power supply matched! The build quality is also good, both the outside case and the electronics appear well made. The LEDs for the CC and CV don't line up with the holes in the front panel."
"My only issue has been with forgetting how the controls default to changing the most significant digit when rotated."
"After the unit is turned on the blinking digit to adjust both the voltage and the current is the left or most significant digit. This means that, for example, if you are using this power supply with a 3.3v system the default adjustment digit after turning it on is the 10's digit and it's very, very easy to accidently turn the knob when you are trying to push it to select the next digit. The unit does remember the last digit that you selected from the previous adjustment which is nice but it does not remember this after the unit is turned off and back on. If there was even a short interruption in the A/C power the unit will come back up to the desired voltage but if you didn't realize this and pressed the voltage adjust knob and turn it thinking you were adjusting the same digit that you just previously did, poof. The second issue is that although the Lock function works great and prevents adjusting the voltage or current when this indicator is on, it does not remember this setting if the unit is turned off and back on."
"However, as others have mentioned, there are some frustrating design flaws that make it dangerous to use without taking special precautions. Changing adjustment units (10v to 1v to .1v to .01v) requires repeated knob pushes WITHOUT rotation. Recommendation 3: Remember crucial options like the voltage adjust units and Settings Lock across power cycles. Issues #1 and #2 would be somewhat mitigated if there were an Output On/Off switch to easily disconnect the supply from the circuit before making ANY setting changes. I opened the unit to see if I could add a switch myself, but it'd be difficult given the main logic board encompasses almost the entire front panel. The only real workaround for these flaws is to manually unplug the positive banana plug before making any changes and then replug it in only after ASSURING the new settings are correct. It is frustrating that what is seemingly a robust and well-built power supply is dangerous to use in real world situations because of some basic human interface design flaws."

"Second, the sharpening stone did a terrific job restoring the edge on my kitchen knives that had been woefully neglected. While the stone includes a useful angle guide that can be attached to a blade and the guide gives clear steps on prepping the stone and how to hold the blade when sharpening, it does not illustrate the manner in which the blade needs to be moved across the stone."
"the knife guide helps me a lot in keeping the knife at the proper angle."
"it takes some learning curves but works pretty good."
"I've never used a sharpening stone before, so am still practicing."

"I just had major back surgery butI bought this before I went to the hospital because I still had trouble picking things up from the floor."
"I was even able to pick up a dot of paper made by a hole punch. A dot of paper!"
"UPDATE: purchased the same grabber awhile ago and OMG it’s been life-changing! I'm also clumbsy and drop stuff constantly because my hands shake so bad."
"The metal wire that pulls the pincers is attached to the trigger by being threaded through a very small plastic piece. The wire at the other end - the pincers - is not visible, but I expect the same style of design there too."
"I stumbled across this grabber and realized (because Amazon told me so) that it was the one I purchased in May but hadn't reviewed yet."
"So if you grab something and pull the grip too hard the tanker rips off and the grabber is broken. **** UPDATE **** : The company Healthsource replied to my review in April 2016 and I did not see it until yesterday (September). Cant change my score of ** since I reviewed the grabber and not the company but I would buy again from this company."
"They put these tight plastic tabs on the package securing the grabber to the cardboard packaging. Update: July 2017 : I gave this reacher to my mother and she loves it because she's using it for the only thing it could be used for, she uses it to pick up dog turds cause that's the only thing it's good for."

Air coupler and plug are factory installed on the air hose to save user labor and to prevent leaks.
Reviews
"After reading TONS of reviews on various air compressors, I knew I'd buy the Porter-Cable version. But I do enjoy home improvement projects and want to buy the best tools I can afford and take good care of them. EXCEPT THAT THE OWNERS MANUAL THAT CAME WITH MY MODEL C2002 (Type 5 - I found this in very fine print on the labels on the back of the tank) SAID ABSOLUTELY NOTHING ABOUT "BREAKING-IN." So I did what some reviewers did and looked for an online manual which can be found at this link: [...]. Bottom line is that breaking-in your compressor is MANDADORY, but it's also a cinch. Here's the exact wording from the online Porter-Cable manual: Break-in Procedure. Risk of Unsafe Operation. (Refer to Voltage. and Circuit Protection paragraph in the Installation section of this manual.). MY NOTE: this is sort of counter-intuitive as you want the valve to screw UP. toward the tank - giving the appearance of being closed when it's actually open. Bottom line: open the drain valve to prevent pressure from building up."
"I live in a rural area and needed a good compressor to air up RV and vehicle tires. I called Porter-Cable for help and got some lady that didn't appear to even understand the issue, so she told me to just return it to Amazon, and that was what I planned to do. But not believing it was the compressor, I finally found on the internet, doityourself.com, where others have been having this problem since 2006. The problem is with the cheap Chinese air chuck that is shipped with the Accessory Kit that comes with the compressor."

Reviews
"I had my bf apply the pads to my lower back and I was messing around with the dials and all of a sudden...BAM! Always start these things with the lowest setting and then move up within your comfort level."
"I had experience with a smaller, less powerful unit bought at CVS, but even that was helpful. (EBL 840 9V Battery Charger with 4 Pack 600mAh Li-ion Rechargeable 9 Volt Batteries). UPDATE Aug. 2017: I've used this unit for 4 months and it got me through a really horrible time where I was suffering from knotted shoulders and trapezius with terrible trigger points that were so bad I was unable to sleep on either shoulder for nearly 4 full months. UPDATE Sept. 2017: Well, unfortunately, the unit quit working a few days before I had to travel, so I was forced to buy another one to replace it. My original review was 5 stars, dropped to 3 while I waited for a refund, and am leaving it at 4 stars because the seller did take care of the issue and the new unit seems to be working fine (although I did just get it a month ago)."
"I get treated by my chiropractor every month with a professional TENS unit for Sciatic Nerve pain."
"This tens unit has just the right amount of power behind it, small size and features to make it a must have for those with MS, muscle or nerve pain. The housing isn't as nice as some of the higher-end commercial units, but the electrical configuration options are comparable. Sometimes I put it on low and just run it for 30 to 40 minutes while I read, work on the computer or watch tv. *It should be noted that this gizmo has decent power output and runs for a long time off of one 9v battery. The pads are comfortable--not overly sticky or gooey but nonetheless result in excellent adhesion. When finished just re-apply them to the sticker backing sheet they came with and reseal them in the envelope to extend the life of the pads."
"Tens units are the best when it comes to muscle pain."
"This is the second one of these to break within a month of use."

"There is a reason these Howard Leight Impact Sport muffs are probably the most popular model of their type on the market -- they're dirt cheap and work very well. We're also big into the night vision world, so I was pleasantly surprised when the Team Wendy ComTac headset adapters worked with these muffs almost PERFECTLY (see photos I've attached to this review). They Howard Leights -- in our extensive experience -- are: MORE durable, MORE comfortable, have MUCH better battery installation, LOOK better, FEEL like they're higher quality, PERFORM better, and now that we've discovered they can use the Peltor helmet mount adapters, there is simply NO reason to ever get another set of the cheap Peltors."

HATCHBOX 3D PLA-1KG1.75-BLK PLA 3D Printer Filament, Dimensional Accuracy +/- 0.05 mm, 1 kg Spool, 1.75 mm, Black
Because of the lower melting temperatures and lack of warping, PLA filaments retain their color vibrancy and are a common choice for displays or small household prints. Spool Diameter: 7.88" - Spool Width: 2.69" - Spool Hub Hole Diameter: 2.20".
Reviews
"The finish has an attractive glossy shine, and the material itself has great dimensional accuracy, making for less blobs and zits, assuming that you have a nice extruder/hot end. But if you want a budget filament that can works for drafts AND final products (for many applications), you can't go wrong with Hatchbox Black PLA. Sometimes peeling off larger prints will leave a chalky white residue on the bottom for some reason, but a few seconds with a heat gun will clear that up no problem."
"After tuning in my Anet A8 printer I have been able to print some very clean objects using this filament."
"Perhaps the first filament that I have purchased that didn't require much tweaking."
"Requires higher temp than what's listed on the label."
"Works great for me."
"Hatchbox filaments are the only ones I use now."
"This PLA filament has been some of the most consistent in sizing and printing that I've ever owned, yet it's still a good price."

"I was able to receive these at a discounted price for review (not free, I did pay for them and they were worth every penny). I'm posting pictures of some of the rocks we cracked open so you can have an idea of what you'll get with this set, but keep in mind that you could get different crystals-maybe even amethyst if you're lucky! I rely strongly on reviews when making purchasing decisions, so I try my hardest to provide honest, solid, and detailed feedback to help others with making their own decisions.I hope that this review was helpful for you."
"I wasn't expecting a hand-picked assortment, but when over half of them are the same rock despite the varieties that exist, it seems a bit odd. But even still, the quality and overall easy-opening of these geodes compared to the other brands I've bought will keep me coming back for more every time I decide to start a new craft project."
"I guess we got lucky and all of the rocks were actual geodes... no duds."
"I was looking for a great gift for the science teacher and knew the whole mug thing wasn’t going to hit the mark for someone who had been teaching for decades. - So I spent some time searching on Amazon to find an appropriate and special gift, but all I really knew about her was she had made science understandable and interesting for the teens in the small private school which was no small feat science my daughter hated science in the past. After giving the gift, we discovered the teacher had a special interest in rocks. She has already made plans to open some of the geodes during a class this year. During my research, I discovered that scoring an equator around circumference and using a hammer/chisel to open produced a better outcome than just using a hammer."

Reviews
"I solved this by marking each unit with a black marker in large numerals. With a little less attention to styling, and more to functionality, the manufacturer could have easily solved this problem."
"These remote control outlets are fantastic! Even though these things work even better than expected, I'm knocking off one point for the two cons below (neither of which is a huge deal, just a little inconvenient): Cons: - These remote control outlets are just a little too big, so if the other plug you are trying to fit in a shared wall outlet is anything other than just a simple plug, it won't fit."
"Although it is possible that I received a different or updated model, I thought I should correct, or rebut, some of the misinformation that I read in other reviews. In another case, I had a three pronged plug that I was using in the spare outlet, which had to be relocated, as it would not fit after installing the remote switch. But, very easy to just add the remote switch into a short extension chord, and the problem is solved. After the Holidays, most of these units will be relocated to my basement workshop where they will be subject to much higher loads and more demanding use. I will use one on a dust collector (about 12 amps draw), one on a vacuum, and even one on a strobe light so my wife can summon me if she needs to, without me cutting my hand off if she yells at me to come to dinner. So now my wife just hits a button upstairs and my strobe light in the basement lets me know she needs me to come up!"
"Additionally beyond that, the remain 4 that were functional out of the first set have been cycling daily (via RPi) for about 4 months now."
"When you plug your appliance into the Etekcity outlet, in this case a lamp, into the front of the Etekcity outlet, the Etekcity body will either cover the top wall outlet when plugged into the bottom of the wall outlet. Or, if you plug the Etekcity Outlet into the top wall outlet you may find it difficult to use the bottom wall outlet if you were to want to use the bottom outlet for something like a Vacuum Cleaner or any other appliance that has a large plug."

Reviews
"By the time I clicked the print button it is already done printing. Easy to feed new labels."
"Cons: Instructions for downloading or creating a template for labels not pre-loaded into the program don't exist. This label does not exist in the most recent software (8.5.1), and I can't find anywhere to download this template."
"This is a disadvantage because removing the lid is not very intuitive and because the electronic card with the power LED to leave exposed and unprotected. Third, the connection of the power cable and the data cable is quite uncomfortable, the manufacturer repeated the same design error that other label printers have in that sense (as in the case of Zebra that I have used)."
"Got a 3rd printer to put over by the kiosk used for printing box labels where they are packed. You could make the case that the more expensive printer would cost less with materials."
"Easier to work with than the twin turbo, and 1/3 the width."
"Not recommended for average person to unjam themselves, I have a technical background and found it rather difficult. Gets only 4 stars due to difficult label changes, some may find ultimately frustrating."

Reviews
"Oh Squatty Potty, You fill me with endless joy, Yet leave me empty."
"I dont know what to do with all the extra time I save now that I poop faster."
"Then it went from bad to worse... adding blood and could no longer pass my rainbow snow cones of Fallout 4 style waste. Usually in a 3 week interval I'd get very sick and spend 3-4 hours in about 9-10 trips of liquid dookie stew and could barely function for the next 48 hours. In fact I think I'm starting to feel better and my cramps are no longer happening. I swear to God, when I go on my next road trip, I'm taking the damn thing with me, and IDGAF if my friends laugh at me. This damn thing may have saved my health and possibly my life."
"You may think I'm just some made up spam account, but I honestly have bought multiple squatty potties."
"I bought this about a month ago for my wife and I, and really wanted to get some good time in with it before I wrote this review. We are pretty healthy people, work out when possible, and have no "problems" when it comes to #2. Sit down, pull it out from the toilet, put your feet up, and bombs away!"
"I gave it 5 stars because it's a 5 star product."
"Maybe it's always been a struggle to squeeze one out with feet flat on the floor, but I never noticed how hard I was flexing my abdominal muscles before owning this product! The better question is this: with the ease in which I now do my daily colon dance, do I care if they are related?"
"Ok, so the Family was looking at me like "ok Dad what now" took a little getting used to, kinda reflected back on my military days of taking care of biz using my entrenching tool -- but guess what, it works!"

Reviews
"I used the white gaffer tape to tape the cable so that it would blend in with the walls and ceiling as much as possible."
"I was in a hurry and ordered this brand rather than the other USA made brand I typically get, since The Gaffer Power tape seemed like a deal and had great reviews."
"I am not in the entertainment industry but use your tape in my workshop for a variety of jobs and and have even found it excellent for attaching sandblast stencils onto custom items which I make. If the tape will withstand 100 psi of pressurized air loaded with silicon carbide grit, it is really tough stuff."
"One of our helpers just pulled the cable up and the tape curled around and stuck to itself. First purchase worked so well that we decided to keep an additional supply on hand for our next production."
"We have dozens of different types of tape in several locations around our home. If you are used to 3 rolls for $1 department store tape, Gaffer tape might surprise you."
"Having fought duct tape for years (I maintain one of the strongest bonds in the universe is duct tape stuck to itself) I had no issues using this to secure my cables at an event over the weekend."
"http://www.amazon.com/Professional-Premium-Grade-Gaffer-Power%C2%AE/dp/B00GZE3UJ8?ie=UTF8&ref_=cm_cr_ryp_prd_ttl_sol_0. This is my first experience with Gaffer tape, so all I can compare it to is duct tape."

Reviews
"Recently I left home for an extended vacation and was about to order a $189 brush when I found an unbiased website that compared and contrasted benefits of electric model toothbrushes."
"My least favorite parts are the built-in timers that vibrates the handle every 30 seconds to let you know when to change areas of your mouth and every 2 minutes (dentist recommended time). PROS: - Rechargeable (lasts about 7 days with regular use). - Spins (doesn't just vibrate). - Comes with base (which is also the charger). -Pressure sensitive (prevents gum damage). CONS: - 30 second/2 minute interval timer can be annoying (at least for me). - Long extension cable that cannot be tucked into the base (cosmetic complaint that may be beneficial for some who have far outlets). - Brush heads will be spent fairly quickly due to the spinning action of brush. The pictures I've provided include chapstick and a quarter for scale."
"After years of issues with weak teeth, extractions and fillings I find myself facing more in-depth dental work. When the dentist talked about their glories and the importance of keeping a few of my "key" teeth, I paid a little more attention."
"It occasionally stutters while using or I would have gave it 5 stars, but at this price i can buy a new one every 2 years and not worry about an internal dead battery replacement like the "100$ and up" ones. Get the real Oral B cross action brush replacements if you like them, as the generic ones are not even close."
"I am very happy with my purchase this was a very good price for this electric toothbrush I have had an electric toothbrush before but it broke the battery did not work anymore this is a great replacement it was brand new I am very happy with it my teeth are now clean again."
"I don't know it there is a problem with the device or that is just how it operates."
"Dentist told me that my gumline was receding due to aggressive brushing (a little OCD about cleanliness I guess)."
"The toothbrush is timed for 2 minutes of brushing with pulses every 30 seconds so you know to switch quadrants of your mouth."

"Etekcity Line of Lasergrip IR Themometers ( 1022D, 800, & 630) compared to Klein IR1000. I am not a Professional HVAC or auto mechanic but I do a lot of work myself on my home and vehicles.. An IR thermometer has many uses. I bought this as a homeowner to verify hot/cold spots around my home. I decided I would go with Etekcity Line IR thermometer based on Amazon Best seller Etekcity 774 (best seller most reviewed and priced very affordable at $16.88). After researching other Etekcity models I found many different options that offered different ranges, features, and spot/distance ratios up to 16:1 with 12:1 being the higher standard and what most higher end brands have.. spot/distance ratios range from 8:1 to 16:1 in this class of IR tool. I submitted a question to them through Amazon and Etekcity responded within the same day offering to call me , as I had a lot of questions..I was able to immediately open a chat conversation with Etekcity customer reps and they were VERY helpful in explaining to me the advantages / differences in all of their IR thermometers. Etekcity 1022D- $19.99 Etekcity Lasergrip 1022D Non-contact Digital Infrared Thermometer, Dual Laser, Blue. my first IR from Etekcity: I like the idea of Dual lasers & adjustable emissivity. Etekcity 800 Lasergrip - $25.98 Etekcity Lasergrip 800 Non-contact Digital Laser IR Infrared Thermometer Temperature Gun, Yellow/Black. Features: Single Laser. 16:1 distance to Spot ratio. Emissivity- FIXED at .95. Range: -58℉ - 1382℉. After a disappointing test of the Etekcity 1022D I read reviews and decided to look at the 800, It features better accuracy at range with a 16:1 distance spot ration. *** Etekcity 630 Dual Lasergrip - $29.99 Etekcity Lasergrip 630 Dual Laser Non-contact Digital Infrared Thermometer, Gray and Black. First impression was how it was packaged in a nice solid cardboard box ( unlike the plastic blister packs of the others including the Klein. The most features, options and in my tests most accurate ( accuracy is negligible between 800 & 630 both are well with in the +/- .5 to 2.0 tolerance). Features: Dual laser for better accuracy. 16:1 Distance to Spot Ratio. Emissivity: ADJUSTABLE. Range: -58℉~1076℉. Multi function menu options ( MAX/Min temp setting, AVG and Diff/ TD). I chose the 630 over the 800 mainly due to the extra menu options ( AVG, MAX, MIn , Diff) adjustable emissivity ,and dual laser aside form that the 800 & 630 perform identically. the 1022D and 774 are priced well at under $20.00 but for more features and higher specs I think one will not go wrong with the Etekcity 800 or Feature rich Etekcity 630."
"This device is probably the best single purchase that I have made on Amazon in my three-plus years of Prime membership. It functions wonderfully as a distance thermometer, shining a tiny red dot on what I'm measuring and, based on comparison with a thermoscan camera at work, is pretty accurate across a range of temperatures from 0°F up to about 400°F. The button that turns on the device has a very soft click, barely perceptible, so it won't distract your faithful (or in the case of cats) persistent companions. *Probably won't reliably measure the temperature of flames at a safe enough distance, so don't get too close to fire."
"I bought this product because I thought my refrigerator was not cold enough, and I saw the tech that previously came out using a lazer thermometer to gauge the temps inside."

"Very durable case, tons of different kinds of screws that will come in handy, and it was a great value when I bought it."

If not (or if you want a spare) you can order the bit here: Kreg DDS 3-Inch No.2 Square Driver Bit and 6-Inch No.2 Square Driver Bit for Kreg Pocket Hole Systems.

"I'm so glad I read the other reviews and decided to order these."
"I've tried using other screws for some pocket holes but they don't screw in as easily and it's hard to find pan head screws which provide better holding power in the pocket locally."
"This has been useful to use as I often get confused with what size screw to use with different types and sizes of wood so I have enjoy this product and it has been very useful and a time saver."

Note: *100 minutes cleaning using Standard mode on hardwood floors; approximately 1 hour cleaning using Power Boost mode on carpeting. Power Boost Technology: New feature automatically increases suction power when extra vacuuming strength is needed to get the best clean.
Reviews
"I've owned 3 of the original, better well known robot vacs and I always felt like none were really engineered to work in a real family environment (area rugs, pets,kids, etc...). I saw a review combined with a low price alert on one of the many gadget blogs I read and I accidentally bought this thing... I'm pretty sure the algorithm for moving around objects in the other robot vacs was better, but the algorithms don't mean much when the gadget can't effectively do its main purpose."
"We have owned several roomba early models over the years, and we have been mostly underwhelmed with overall suction, noise, and pickup power for the $300~$500 range robot vacuums. Skeptical but curious, we picked this "little RoboVac that could" on a whim, without expecting much given its' very reasonable price. This overgrown hockey puck eats more socks and stray underwear than our dogs! The suction on this compact little dust demon is so strong that the exhaust port on its side, makes our curtains billow from 5 feet away, while on MAX mode. In standard cleaning mode, our Euphy runs well over two hours on a single charge. Full disclosure, I sadistically tucked away the charging station three rooms away. This little dust, dirt, dog-hair, underwear, sock, phone charging cable gobbling little robot vacuum."
"The Eufy has only finished one vacuum cycle, so I clearly can't speak to longevity, but just some general early observations for anyone considering this brand new model. It picked up a lot of cat hair that the Roomba wouldn't have, and the floors look just as good as they do when we do a full vacuuming. The one issue I did find with this was that for things like chairs with dust ruffles, the Roomba would have gone right through the dust ruffle to clean under the chair, but the Eufy views it as a solid vertical surface and turns around to go somewhere else. Overall we're very happy with it so far, and my mind is blown that in three years, Anker managed to make a vacuum so much better than our old Roomba at around half the price."
"Great alternative to a stand-up vacuum."

"Probably not necessarily a good thing, but I revamped my closet with these instead of donating a large portion of clothes to Goodwill (although I had already donated two other closets full until a friend recommended these hangers) and now my clothes all fit neatly!"
"I have had some minor issues with a few of these breaking when I'm taking things off the hangers, but I'm also not the most gentle with them when I'm in my daily morning rush mode."
"I am a small/size 6, but these hangers accommodate men's clothing as well."
"I love these hangers because they prevent my shirts from falling off and onto the floor as I'm trying to find something to wear in the morning."
"This pack was perfect for my dress rack, which never seems to have enough hangers."
"These hangers are great."
"I rely on reviews and I could not believe the quality of these hangers when I received them."
"The minor reason: Every hanger has an imprint into the chrome handle announcing the country of origin in capital letters. I have no issue with products made in China, but having to read this in capital letters on each and every one of my 50 hangers is a little too much."

"Like most of modern day Dewalt stuff, they are made in China from Chinese steel. If you want the best, payseven times as much and purchase from a reputable American manufacturer. Some people give less than five star reviews for these bits complaining that they are cheap Chinese junk. I can't understand reviewers that buy a $10 tool, then complain because it is of lower quality than a $50 version."
"I bought this set several yrs ago for myself first, and they have done what I'd expect from them."

Reviews
"Results: faucet tap= 328ppm. aquafina bottle water= 2ppm. kirkland (Sam's Club bottle water) = 20ppm. and the apec water = 25ppm."
"I was impressed upon opening it as the main filter housing unit seemed very high quality and heavy. You can push the lever down and hold it if you just need to fill a glass or you can flip it up until it locks and and it will continually dispense until you turn it off. Some of these faucets require a 1 1/2" hole, and that would concern me because I have a synthetic granite/composite sink that it tough as nails to drill into. TIP: Once you locate where you want the faucet mounted, get a thin piece of wood (such as a shim) and drill a 1/2" hole in it. In my case, it took me a good ten minutes to drill through my sink (probably a 1/4" thickness) and the bit was completely useless once I got through the surface. Once the hole is drilled to your liking, follow the illustration for assembling the hardware for the faucet and mount it. I have a 2200 square foot ranch that was built in the eighties with that nasty, defective polybutelene plumbing and, after a ruined master bath and another close call in the kitchen after owning the house for just 6 months, I had my plumber completely re-pipe to the tune of 5K. If you decide to do this, the only one you won't be able to use one on is the yellow line that goes from the RO unit to the tank (because it has a crimped-on special two-way valve). One word of caution though- if you do this be very careful and mindful that you are screwing a metal compression connector onto plastic threads on the unit. My advice, in hindsight, is to determine where you're going to want the unit and place it there prior to beginning the install. It took me longer than it probably would have taken most people, but I have a unique kitchen sink with funky plumbing (couldn't use 1/2" adapter included to feed system from faucet bottom, instead had to convert down to 3/8" and run from cold water valve)."
"We already had a separate "beverage faucet" (with simple inline carbon filter) mounted on our sink so it was pretty much plug and play. I'm using a Watts Premier 560087 as the 5th stage filter (last is the carbon filter) in our APEC ROES-50. Never had acid reflux before with our inline filtered water used to brew coffee. P.S - I know APEC makes a remineralizing/pH filter, but the Watts filter contains additional minerals such as magnesium and potassium, whereas the APEC filter is just calcium. It installs in between the tank and the tee, vs the 1-way "final filter" of the APEC (probably why it doesn't raise the pH that much - water passes through it too quickly). The tee just replaces the 1/4 x 1/4 x 1/4 existing tee on the RO system For the 3/8" final filter, I really like the Hydronix filters, I used B00D04BYIK (again, search on Amazon), but any 3/8 inline carbon filter will do."

"2 speed, with a small led light to help illuminate the working area."
"It takes care of all my drilling and screwing needs while building my Hollywood style Lighted Vanity Mirrors."
"Got this for my husband because his 12-volt Dewalt from circa 2000 was just too wimpy compared with their 18-volt drill I bought a few years ago. Saw this incredible deal (buying 2 batteries would cost nearly as much) and had to get it for him as a early Christmas present. It is shorter front to back than our previous DeWalt cordless drills, making it easier to get into tight spaces. While I will admit, it is hard to find an accurate, small spirit level that you can attach to your drill to affirm you are vertical, even if you could find one, there is no flat surface wider than an inch or so to attach it to and all the spirit levels I have seen on Amazon (excepting the round ones) are 3-4 inches long."
"Drill bit chuck definitely has a slight wobble, and is visibly more acute with longer drill bits."
"Mine had "DCD777 TY1 / 2017 15-47" in the two units I got from Amazon and both of them had the same issue, despite sending DeWalt two messages via Amazon, they never replied. I will definitely keep out from this drill, buy another one from DeWalt if you like the brand, but NOT this one."
"I'd had a mid 90's Dewalt 12v drill driver that lasted until this early this year until it's batteries both finally died and this was to be the replacement. While I give credit that they still offered the old replacement NiCad type battery - I thought it was time for a new drill. I checked two other Dewalt drills at the local store, the 12v and I think the next 20v model up with the metal chuck and they also had the cheap wonky switch."
"I am extremely upset with this purchase and may never buy a DeWalt product again."

Gallium Metal 99.99% Pure 100 Grams Get it in 5 Days or Get a Full Refund
A soft silvery metallic poor metal, elemental gallium is a brittle solid at low temperatures. Gallium From RotoMetals Inc is the purist and best to Use!
Reviews
"Un fortunately I used my electronic scale that was finely calibrated to weigh the gallium and it weighed 100g INCLUDING the plastic test tubes."
""They called it 'pure' potassium, but it turned all white when I exposed it to air, and when I accidentally flushed it down the toilet the pipes exploded! "Love the radium, but I can only give it three stars because it caused horrible burns on my hands and gave my wife cancer." Gallium is what it is - a shiny silver metal with a melting point of just over 85 degrees F - and it gets five stars for it. I melted mine into a plastic cup and left it in my office overnight. I just enjoy it for what it is, a curiosity for my office to sit next to my Buckyball magnets, my fire-spitting wind-up nun, my musical LED top, my green laser, the rubber chicken that produces an egg out its rear when you squeeze it, and various puzzles, magnets, squishy things, nesting dolls, and other things to inspire me as I work."
"But keep in mind that this metal really likes to stick to your hand when melted and getting it all the way off is pretty hard. Secondly, you can't melt it using traditional methods like a stove or fire because the container is plastic. You need to run it under hot water for a long time in order to get even a little bit out of the container."
"awesome stuff."
"It solidifies again at room temperature but that can take a really long time due to known supercooling properties of gallium."
"It's fascinating-I don't know what you'd use it for but I'm simply happy to use it for stress relief by playing with it randomly."
"Really fun... use a place mat underneath.. leaves a tiny mess but comes off with hot hot water."
"Really cool stuff to play around with."
