This is a good small ratchet clamp FOR CERTAIN THINGS. It works on flat things, but it doesn't do well on any thing that's round or curved. The wobble-head ends make it want to slip off the project too easy. It seems like all clamps now days have "wiggly" ends. Rigid ends would be preferred on most of my projects. In fairness to this clamp, it DOES  do what I got it for VERY well. I needed it to squeeze the lock on a  cam-lock cinch strap .
