Pros: Very sharp protective sheath Cons: Can use some beginner's instructions Bits arrived well packaged in their own plastic storage case. Unfortunately, if you have never used these types of bits before, you may be a little confused as to how to use them properly. I think these beats are suitable for both beginners and pros; However, due to the lack of instructions, I have to say that it will be easier for a professional to use it straight out of the box. I would suggest including some simple instructions. They don't have to be fancy, just a general guide, maybe with a few pictures. Otherwise the set worked great and would be a great addition to my woodworking tools.
