Stun guns are a nifty idea in themselves, but making it look like a mobile phone is a master stroke. Not only is it disguised, but mobile phones by themselves have been known to deter would-be attackers (e.g. during the Sydney Gang Rapes http://en.wikipedia.org/wiki/Sydney_gang_rapes, the perpetrators apparently decided not to attack girls who were talking on mobile phones).
