I bought this as a freestanding vise for my guitar shop and I mounted it on swiveling stand in the middle of my shop. It's nice and heavy and the jaws open and close smoothly. They also rotate very smoothly so I have almost infinite positioning possibilities. Once the jaws have gripped, they stop rotating and the vise holds the work piece still with moderate clamping pressure (as opposed to some where you have to crush the work piece to get the vise to stop rotating). I still have a small vise on the bench but I use this big one constantly. Very sturdy well designed product.
