Cell phone stun guns, like any other stun devices, are an extremely effective form of self-defense that may be lawfully purchased and transported in the majority of areas within the USA. A cell phone stun gun appears completely similar to an actual cell phone as it allows the user to carry these devices and never have to feel self-conscious about noticeably holding a weapon of self-defense. http://tasergunsforsale.net/cell-phone-stun-guns
