If you are planning to get a stun gun, you definitely want to know it is going to work when necessary. I have actually never utilized one before, but I certainly see how they can be a weapon of personal protection. Nobody wants to have to use one, however we all need to be protected. Maybe a stun gun is a much better alternative than a gun or something else because one of those particular devices is a non lethal choice. It just really depends on what you feel at ease with. Pepper spray can in some cases be simpler to carry and utilize probably, but a stun gun might be more effective.
