Good enough for home use. I haven't checked it on a surface plate yet. Don't expect a kurt equivalent vise for $100. Unless your machinist Jesus, that's just not gonna happen. Overall: pretty good for the money
I'm in the business of selling vises. Bought this one for my garage shop not needing the $500.00 vise. Was very happy when this arrived. Ran it thru it's paces and works great..
