I have none of these. The other Bessey gear clamp kinda put me off of Bessey clamps except the good old square headed bar clamps.
I have several of these, and while I like the concept these are junk next to the Jorgies I popped in your caulking gun clamp.
My Bessey gear clams are these. I see Bessey calls these a Klikclamp, anyhow junk compared to what Jorgy calls a gear clamp.These cost way more than the Jorgies too. There should be gubmit protections from makers who practice, clamp gouging. :-((((
