I've only been SR shaving for about a month effectively, but I'm loving it. Not getting that BBS shave yet, but I'm certainly getting closer. I've never been excited to shave before, but now I can't go more than two days without getting back at it. I think I am, however, starting to get addicted to the buying of razors as much as the using of razors. As far as problems go, it's a pretty nice one to have.
