TENS 7000 2nd Edition Digital TENS Unit with accessories
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."

Wireless Endoscope, Depstech WiFi Borescope Inspection Camera 2.0 Megapixels HD Snake Camera for Android and IOS Smartphone, iPhone, Samsung, Tablet - Black(11.5FT)
Reviews
"I bought this inspection camera for my Dillon XL650 bullet press to be able to inspect brass bullet cartridges while reloading them."
"I was able to snake this thing up there and see everything that I was doing with my hand, and also lay under the car in a comfortable position while I watched what I was doing on my phone. Most of us are carrying around super high quality video monitors in our pockets, so I decided to give this device a try. Also those more expensive units have the cable connected to the screen which is usually mounted to some kind of handle. I have a magnet attached to the back of my phone and it just stuck right up to the pan on the bottom of the transmission. As to durability, I have only had it a week or so and it's holding up so far, although I can envision some problems over time with repeated flexing of the cable. The view you get with it is just like with your phone camera, meaning if you rotate the scope clockwise, the image will also turn which can be disorienting. I got the camera in the right orientation and then bent a "W" shape in the cable a few feet back from the end of the scope. The app allows you to show a mirror image of what you are scoping and you can get rid of the icons on the screen so they don't interfere with what you are trying to look at with the camera. Pros: Price, image quality for live video, stills and captured video, long cable length, WiFi connectivity. Cons: Cheap WiFi box, barebones app, resolution not really changeable."
"1) It does require that you download the "Wifiview" free software to use with this, and either charge it well or keep it plugged in. 5) If you weren't able to get this far or just see a black screen, double-check check the power switch, and try adjusting the brightness of the LED lights. 6) When you begin recording video, check the top of the screen for a digital readout (red font) of the time that you have been rolling. It appears on the screen, verifies that you are recording and helps you control clip length. We have also used a wire hanger to guide it for longer horizontal expiration, such as ductwork. If you require inspecting a longer length of this sort of passageway, you might be able to attach it to twine that you have already run through and then pull it along. This just meant paying attention to the screen to see what we were getting, and adjusting the distance from what we wished to see clearly. The task involved some tight spaces, such as in and around electrical outlet boxes (be safe), and we were still able to adjust with ease and an easy-going attitude. At times we chose to supplement the lighting to look further down the path ahead, or to highlight texture. The additional light (bright flashlights) worked well with this product & didn't wash out the view. 13) The software download will allow you to play your videos and view photos just by navigating to them and tapping what you'd like to see. The ground shook, there were screams, and loud organ chords and strobe light as we found..... Well.... OK, maybe just darkness fell over the land, and maybe that had something to do with the 2017 solar eclipse, and it was still just the chill to go along with the mystery object that will remain exactly where it is in the wall because nobody I care about is allowed to touch... THAT. Most of those little it's have to do with the software, and then I'll acknowledge that I can appreciate a functional no-frills approach over redundant or unnecessary bulk that takes up precious memory space. Dropping your phone or tablet could wipe out the DIY savings rather quickly."
"Really impressed with the Depstech Wifi Endiscope."
"For the price it is fine, but if you're looking to use it for serious inspection inside of things, be sure you have a light to chine into the item or run in separately."

Etekcity Digital Hanging Luggage Scale, Rubber Paint, Temperature Sensor, 110 Pounds, Silver
Etekcity's digital luggage weight scale is designed to save you stress and money when traveling by airline. When all is done and taken care of, its lightweight and portable build makes it easy to slide the scale in any small pocket without adding extra weight.
Reviews
"I put a brand new battery in for a trip at the beginning of September and it was dead by the 14th."
"I upgraded to this from an analog one made by Samsonite which still works great , but on that one , needed an additional pair of eyes to actually read it , with this it is more accurate since its digital and avoids any parallax errors and also can do this single handedly."
"What makes it convenient is that it can be used by a single person or in a tandem, where two people lift the scale while it is weighing the luggage."
"Accuracy/precision arguments aside, if you're close to bag weight limit on this scale, take something out just in case."
"I have always had trouble weight large suitcases when traveling abroad."
"I've used this with four suitcases and it's reading is exactly what the airlines scale read (Delta), if I rounded the decimal up."
"The display has been easy to read and the strap seems strong enough to hold loads while it weighs."
"Turns out, we couldn’t get it to work because it it’s too heavy to lift and stay steady enough to calculate the weight."

Best Power Transmission Chains

Koch 7435100 Roller Chain, #35, 10 Feet
Koch Industries standard roller chain is a long life chain that will work with standard sprockets on agricultural and industrial equipment. Standard roller chain meets ASME/ANSI B29.1 standards.
Reviews
"worked perfectly for what I needed.....seems the description didn't mention it comes with a master link, so that was a nice surprise."
"As you can easily confirm by thought experiment or actually trying it, roller chains generally need to be fastened to both ends of the gate to work properly. The link itself fit properly and was easy to install, once you remove one pin from the stainless roller chain. An effective way to do this in the field requires a hammer, a punch, and a hex nut."
"While using my snow blower last winter, I found a couple rocks that I wish I hadn't, and the end result was breaking my snow blower's drive chain."
"I put the predator 6.5 hp on a mini bike that only had a 3hp."
"so far so good."
"This worked great for my #35 mini bike chain."
"The drive chain for the hatch on my Chrysler mini van broke and I could not fine the right size link anywhere."
