It's not the be all end all vice. It is aluminum and is a middle ground vice. If you're looking for a heavy duty tool this isn't it. However it does lock up very tight, doesn't seem springy with a double shotgun in its teeth so it will serve the every day uses like cleaning, putting on a scope, and other small to medium jobs. I do agree however that some of the plastic will most likely break at some time and then I'll be cursing trying to find a replacement.

Nothing is foolproof to a sufficiently talented fool.
