Pros
I purchased three of these for our stained glass classes, and they get a lot of use. They seem to be better engineered and stand up to student abuse better than the Wizard grinders we also use.

Cons
Top is hard to get off to clean the water reservoir. Twofer bits don't fit these grinders.

Other Thoughts
Studio Pro bits are the only ones I have found that fit. This brand only come in really coarse (Fast Bit), or really fine (Standard Bit), there is no grade in between.

Pros
The cross is a good size for the really small scrap and chips I tend to get as jewelry off-cuttings and large enough it doesn't feel like it will snap as a necklace.

Cons
The post on the one I got was really weak. I used ZYP and sprayed from every angle, but I still lost the post on the second use. It came out of the finished piece, but it didn't stay attached to the mold.... I've just been wrapping a piece of nickel chromium alum wire with fiber paper and putting it in the hole of the first one. That works okay, but I still have to clean up the hole and I'm always concerned the jury rigged set up will fail and it will leak.

Other Thoughts
The original hole ends up so big that it kinda throws off the balance, I actually like my jury rigged version better when it comes to size because I can keep that to a smaller, round hole that I put a finding through. But I'm still considering getting another one in the hopes that it's not so weak.
