Good bits and case. Actually they're all cobalt, but some of them aren't engraved, just laser engraved, which is a bit annoying. Some of the ones don't have "US" engraved on them, meaning they were probably not made here. but overall if that's all I can complain about. I think they are good value for money. It would cost at least another $100 to get a more reputable brand with all the bits engraved that I can live with.
