Maybe I expected too much from them but the threads on the bolt break even when tightening a 2x4 jaw with moderate force. It no longer fires after a quick trigger, I have to turn the knob a couple of times before it fires. The clip itself is cast aluminum, on large stock it won't hold a corner, even on lighter wood like pine. I used it with white oak and it was 4 degrees at 6 feet. I wouldn't recommend getting this. Spend more money and get something better.
