Not a whole lot to say, it fits. And the price was more than reasonable

I don't need one of these things very often, so don't mind saving a few bucks on one. Found dozens and this was the most inexpensive of the lot. It works exactly as it should. Maybe a hex shank would be better than a smooth round shank, but not complaining for the several dollar cheaper price of this one.

Well machined with good quality. I really liked the fit and the machining on this adapter. I chucked it on my drill and used it immediately. Very handy to have for quick touch up work. But sturdy enough for continuous work.

This adapter works great for connecting large diameter hole saws. My only wish is that it had a hexagonal shank rather than a round one, so it could be used with an impact drill. That said, it still performs well with a drill press or hand drill. A solid tool for the job, but with a small improvement, it could be even better!
