The quality of the bits is fine. No complaints there. I guess I didn't read the breakdown of the sizes as I was excited about the sale price. My complaint is that this set has no normal sizes. They are all something & 1/16. So no 3/4, 1, etc. It is almost as though this set is meant to be a companion set to something else and it just may be my issue for not reading the description more closely. If you are ok with that, then purchase. If not, pick another set.
