It appears to be a well-designed jump drive, but the extra features seem more of a gimmick than really useful. The ruler is in centimeters and completely unmarked, the keychain portion is too small for my keychain, the utility knife portion is too blunt to be effective (but honestly, you wouldn't want it too sharp in your pocket now, would you), and I haven't tried the bottle opener yet. The magnet works and is practical. I have metal cabinets around my desk at work and it's nice to throw them in there. I'm giving it three stars as it's comfortable but still a bit disappointing. Decent topic of conversation
