As a woodworking instructor and retired contractor, I like these clamps, but with average hand strength, these clamps can be easily overtightened and the tightening mechanism broken. When I purchased these clamps, I thought they would be covered by the standard Craftsman hand tool warrant.....Wrong...The warranty is good for only one year. However, with moderate use, they are a good clamp.
I'm very happy with this clamp. It's easy to setup and to release and holds things in place very effectively. I wish they could keep them in stock so I could order another one to go with this one.
I order this on 4/7 and they finally shipped on 4/18. No wonder Sears is closing.
