Well, I've definitely read through that multiple times, and I can DEFINITELY tell that it's cutting hair. I have tried multiple times to get that "popping hair" (both just down the arm as well as dropping a hair on an upturned blade) and have never attained it. So is it "sharp enough" that it's doing something but not sharp enough to get a BBS shave? I don't feel scared at all about shaving under there, I feel confident in my ability to shave there, I'm just wondering why it's not getting it as smooth as my ol' cartridge did.
