Popped off the bleeder screw, then fell apart.

Bought at a local auto parts store on the recommendation of the counterman - returned 30 min later after it had popped off the bleeder screw once, and come apart from itself after reattachment. Used the simple hose and reservoir method with no trouble.

Cheap crap.  I bought one and while putting in the second mounting screw the head of the screw came off, leaving the rest of the screw in the case.  The third screw did the same.  While trying to take the first screw out ITS HEAD SHEARED OFF AS WELL!

I figured there was no way I could return it since I had clearly been an idiot, so I ordered another one.  The one came to me with one screw already sheared off in the friggin mount.

Please stay away from this crap.

This broke in my hands. After the third threaded insert into wood, the end of the wrench began to bend. I bent it back gently. On the next threaded insert, it completely broke off.

Save your money. Just use the bolt that you wanted to use with the threaded insert and use a screwdriver.

Worked, but fell apart regularly- lost half of it in a day. :(

It fell apart the second it was delivered; i tried another screw, to no avail.  This is either a bad product, or I just received a broken one!

As I was loosening the adjustment screw so I could swivel the socket ... It simply fell out ... turns out, The screw and the threaded hole were both stripped so it could not be used ... The other holder had some thread damage but could still hold ... cannot install this thing like that ... Seems by the looks of the threads ... it might have been either returned and re-packaged or put together VERY poorly ... Needless to say, I am very disappointed ...  I have installed/repaired  countless floodlights in my life time ... The best design I've ever seen was an elegant thumb screw for adjusting the socket angle ...

Arrived with screw having fallen out from one leg (no problem, I'll just screw it back in. won't stay, it's stripped). I didn't even get a chance to come up with an alternative fix to the bad screw when the rest of it just gave up the ghost and fell apart. I'll be using it as kindling for my outdoor fire pit.

Looks great, fell off after Andy of shooting though. Screw stripped and will no longer tighten. Waste of money unfortunately.

Not for use in heavy duty situations, broke while we were threading 3 inch pipe

This worked fine, that is, until all of the screws fell out in about 3 weeks. I noticed that they were loose, so I figured I overlooked it the first time, and tightened then down to the point where I right I was going to strip the heads. It didn't matter, they fell out a month later. I haven't been able to find replacement screws anywhere.

Bought this a little over a year ago.  I used it about every other day with my Iphone 6.  It stuck to my windshield well, but wobbled fairly regularly. Yesterday while driving, my phone and the part that holds the phone flopped off of the base at the hinge, as though defeated.  Ten seconds later, another tinkle as different piece fell.  When I got home and looked at my phone and the little holder, the rest of the plastic screw on mechanism broke off.  I'm a woman with normal hands, not the incredible Hulk, so I dunno.  This product gets two stars because the sticking backing piece is still on my windshield, mostly because I can't get it off.

i am a heavy duty diesel mechanic.  I bought this in a pinch because i needed something cheaper then the 900 dollar one from snap on. i loved it when it worked.  the clip and the internal guts keep falling out. after the first use it fell apart. i repaired it several times and after one to two uses it falls apart again. the trigger system is cheap and breaks real fast. honestly i would prob find a diffrent brand if your looking for something that will last.

I needed an ornament stand to display ornaments at a craft show.  I took this out of the box at the show for the first time and it was pretty easy to arrange.  I tightened the screw once I got it where I wanted it and then hung my ornaments on it.  From folks taking ornaments off (not pulling or anything, just slightly bumping it occasionally) it came loose and would get really wobbly.  I had to keep tightening the screw.  Not that big of a deal though.

After the 3rd craft show I took this to, it was falling apart.  The screw wouldn't stay tight at all anymore, the paint was chipping, and the "branches" wobbled.  All I had ever done with this thing is arrange the "branches," hang ornaments for a while, take them off, and put it back in the box.  That's it.  Very cheaply made.

The threading was bad and it literally fell apart during the first use. I'm hoping I just had a defective one and that that's not the standard craftsmanship of this item. If so, buyer beware. In the middle of the return process now.
