BETOOLL Pro Universal Ball Joint Separator
Enter your model number to make sure this fits.
Reviews
"Well, it was much too large for my application (a Saab 9-3) - the press would not fit between the axle cup and the ball joint stud and the fork wouldn't fit between the ball joint and lower control arm. I imagine most people shopping for a $15 tool are going to use it once or maybe twice ever... if you're shopping this class of tool for a professional environment you're doing it wrong."
"Used the tool to break loose some ball joints on a Teryx 4 UTV to replace a torn CV boot."
"only big enough to remove tie rod."
"Looks like a nice tool, but it does not work on a 99 Ford F350. The jaw does not open far enough and the clamp is not wide enough."
"I'll give 3 stars as being well made."
"I have used this four times without issue, works well, hopefully it will stand the test of time."
"Ever fight a ball joint?"
"Put this to use as soon as it arrived and it made for a quick job."

Reviews
"- Wood handle won't heat up if it's left in the melting pot. Overall, this ladle works fine for what I bought it for. I would recommend this ladle, but just note the shortcoming's I've mentioned, and you won't be disappointed. Feel free to comment and let me know if I have helped you, and please note below if this review was able to help."
"I still use my bottom pour pot for .45 ACP/LC bullets because they're much lighter, and I can cast more and get more consistent results."
"Ok got exactly what was shown but picture obviously setup to mislead."
"good for dealing with very small amounts of melt casting (pewter)."
"If you already have a pot....this works ok."
"Does ok but it would be better with a flat side."
"works fine, but after a short time the finish is coming off and slag and dirt is stuck on it and wont come off."
"Picture is misleading, this is a very small ladle."

Reviews
"We lost the key for the original lock on our HON file cabinet and purchased the HON F24 to replace the lock."
"Customer service is great they e-mailed me to verify I was buying the right lock, I e-mailed them a picture of the Hon file cabinet and old lock and they verified it."
"First I watched the Youtube video but be aware, they show a slightly different model so stick with the printed download."
"I received mine with instructions and an oversize hole adapter (neither of which I needed -- I already knew how it worked, having removed the old lock previously to install into another file cabinet)."
"The two keys come in handy and the lock itself can fit most cabinets with lock holes."
"I was very surprised and a tad annoyed when the seller called me within a few minutes of ordering, wanting to know the size of the lock opening and whether I really wanted the product I ordered."

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."

Reviews
"Kind of tricky to get used to, but after a couple screws you'll be just fine."
"If you buy a impact driver, this, and a cheap impact driver kit (like 30$) you will have a great set up."
"I purchased two of these at christmas as presents and they work great to get to the nooks that a regular driver cannot reach."
"It is challenging sometimes to change bits and the plastic side support handle is a joke."
"I read a few reviews that talked about stripping out the gears so i dont let my buddies with 18v and 20v impacts use it."
"Great tool for getting into tight spots."
"It certainly delivers access to difficult to reach areas and the fast release is another plus, but none of that matters much due to the quality of the internal gears, which I managed to strip after 2 light-weight uses of the tool."

Reviews
"i did not receive DAL props, and i've never tried them, so i can't compare these to DAL."
"What I do know is that I have broke 2 pairs of carbon fiber props and all the props that came with my quadcopter in just 2 days."
"These crazy pony props are actually Dal unbreakable props really nice quality some you can tell are a lil tight on the shafts while some go on easily and for some reason one of these props broke my bell shaft but they really are unbreakable they just bend easily so on strong power thrusts, they will flex and on crashes just bend them back."
"They do brake but after some abuse .on a regular day out .i brake any were from 5 .to 10 props of inferior quality.with these .2 props in 2 cesions .thas damn good in mi book saves me money .and time .love them .get a bunch and you wont need to re up on props .in a long time ."
"They generally only break if I run head on to a tree or hit the concrete."
"Genuine dal."
"These props are reasonably balanced but they are very flexible and break easily."
"definitely not as durable as dal props."
