I purchased a stun gun awhile ago, having said that i wasn't pleased with it. I never had to use it, but it was only cheaply made and so i really didn't think it might work generally if i did want to use it. I went on the web and sought out high voltage stun guns on the market. I browsed several of the websites and considered pricing for them. In addition, i checked over the reviews. After reading about one gun especially, I decided to acquire it. The retail price wasn't that high along with the shipping was free. I am really happy with the stun gun I received.
