Mounting the vise now.
First tip: Ignore the instructions. Drill a 5/8" mounting hole, 2" in from the front and 2 - 3/8" in from the side of your bench (optimally). The instructions say to drill a 3/8" hole, 3" in from a corner.
(Now why didn't I measure the bolt first before I drilled a 3/8" hole? Grr.)
Edit: Okay, had to tap a 3/8" dowel into the hole and re-drill a 5/8" hole. No problem.
The jaws on mine close together evenly from top to bottom, so no problem there.
Haven't noticed any issues with the bolts or the handle, but to be fair, I haven't really used it yet; just mounted it and played around with it a little. It is cast pretty crudely, and the thick black paint is chipped in a couple places, exposing the metal and allowing a little surface rust. Nothing that should hurt the functionality of it though.
If I'd paid $130 for it I would have been disappointed, but at $60, I'm good with it.
