Yeah, it's "ok"
I got some of their Aloris copy dovetail tool holders. They're definitely sloppier in the dovetail (gotta swing the lever noticeably more to snug 'em up) but they work and the price was incredibly low. edit: also metric set screws of course where as OEM would be fractional
When I was in school circa '07 the coax indicator they sold was identical to the one Enco sold for triple the price
