For a light vise, this works well. I would have liked a better locking mechanism. I had to enlarge the holes on some of the battery terminals and I used a vise to hold them while I drilled them out. Although I tightened the set clamp as tight as I could, the vise head spun with the drill as soon as I started drilling. I would be concerned about doing anything with this vise that puts a lot of strain on the head as I don't trust the clamp very much, but it's great for light duty tasks.
