This thing is so cool I'm crying I didn't open it 30 years ago. Super good quality, does what it promises. I'm so glad I bought this instead of one of the cheap Chinese mini vises. This is one of those products where you still get what you pay for. I bolted it to a piece of steel rather than a tabletop so I could clamp the steel tube in a large vise so it didn't get in the way when not in use. prefect for fine gunnery; soft enough to hold the bolt or frame and strong enough to knock out stubborn roller pins. Can't recommend enough.
