If you're talking about their bar clamps, I bought about a half dozen in 18" and 24" sizes when I was working on my kitchen cabinetry. They were cheap and I needed a bunch of extra clamps at the time. I believe that all but one have broken. There is just not enough meat in the plastic to deal with the forces applied. To be fair, I expect a lot from a clamp and probably over-stressed them. My Wolfcraft clamps have held up through the thick of things without breaking. I also have four of the old fashion screw typ bar clamps from HF and have not had a problem with them.I bought a couple of those hand, squeeze-type clamps from HF. You know, those black, plastic ones with the orange pads on the clamping fingers. Can't remember the size exactly, but about the medium size ones. Anyway, I went to use them a couple days ago and immediately, after placing one of them on the two pieces I wanted to clamp together, the end of one of the fingers broke off and went flying across the garage. It wasn't just the orange pad that came off, it was the black plastic finger that snapped. I do not believe I was overworking the clamp. I used the other one and it did its job. Perhaps they can be inspected carefully before purchasing to look for defects.
I know right.I always seem to talk myself into getting another one when they come on sale for $99.
You got it right not made for professionals, so many don't get that. Some of the tools like impact sockets are pretty tough, just have to look them over first.Cheap tools built cheap for occasional use by hobbiests
