I was surprised how sturdy this feels. I havent used it for much yet, just a few small things. I lined the inside jaws with leather to make them non-marking. But I move the whole workbench before I move the vise. The one thing I dont like is theres a big fat weld inside the clamp that goes past the corner and makes it so the vise sits cockeyed on my bench. Its still a good value, but it isnt perfect.
