There have been a few user comments on their bits and one tool review from a pro. All have been good as best I recall. I bought 3 that were architectural bits that I haven't had a chance to use yet but they look very good. The carbide is thick and soldered on to the body well, they are well sharpened, and even the paint job is well applied.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
