This case holder came very quickly today but I wish it hadn't. The item I received from MCLOCKS had been clearly used (there were tooling marks all over the aluminium vise) and was quite dirty. The pins sit quite loosely in their sockets and cant even at light tightening. The machining quality of this device is apalling, I could have made a better vice with a mill and a lump of aluminium. The crowning achievement of idiocy in this item's design is that the knurled bolt that's used to tighten the vise grip extends to lower than the holder's base, meaning the damned thing can't even stand on a level desk. I kept mine because despite looking like a reject it still worked, and the uneven base doesn't affect me as I mount it in a larger vise anyhow, but if was worth more than twice the postage cost I'd have returned it.
An incredibly bad piece of machining, buy something else.
