It does exactly what I expected, holds the material in place while I use the drill. It all comes out pretty blurry, to the point where I had to erase some of it, but it doesn't matter. I've been drilling through old hard drives to test this and these vises added a bit of weight but also allowed me to drill with more confidence. It also spins easily, but this is probably where I need to make sure it stays lubricated. All in all a great addition to my drill press and just what I needed.
