I live in the city and I am often worried about walking home alone at night by myself. My best friend just told me about a new self defense product that she ordered and I think I may get one as well. She just purchased a Runt Stun Gun. It is a really small, concealable stun gun. It can be worn like a pager or held in the palm of your hand without anyone seeing it. It comes in 350,000, 650,000 or 950,000 volts. The unit also comes in a rechargeable 950,000 volt model. I think she got the 650,000 volt model. I will probably get the same one. I hope I never have to use it, but I will be prepared in the event that something happens one day.
