I don't know what these bad reviews are talking about. They cut pencil shavings out of everything I pierce which shows they are pretty sharp. I've only used them on a couple of projects so can't comment on how long they'll last, but I have a woodworking shop and once I feel like they've taken a decent beating I'll try to go back and check them out further. It's not like this. These are the highest quality Forstner beats you can get from a place like Rockler, but they definitely do what you want them to. They cut perfectly, leaving a smooth cut with no jagged edges and a smooth bottom.
