This is a really good bit set for average use. They're real and sharp, and their variety gives you just about any type of cut you'll ever need. I received it with a very small crack in the clear plastic, but I was expecting worse. Actually it's not that important. I can substitute another clear piece or a small piece of 1/8 plywood. The bits engage well and cut great which is most important - I bought the bits for actual use not to brag that I bought bits.
