I’m finally about to mount the same one. Got from grizzly on sale at $25 but seen elsewhere for $100+. Feels solid, no quick release, but will be a vast improvement for my bench which is an old section of bowling alley. It’s got a large capacity so I’m just turning the 2 rear supports to put on back side of jaw and adding a 3/4” board between bottom mount and bottom of benchtop to allow a bit deeper jaw face. Bowling alley is only 2-3/8” thick so a bit lean on face depth..
