My wife agreed to take a taser along with her, when she goes jogging, and walking at night. My problem is, I have no idea of what to get her??? I don't want her to get into a situation that she was forced to use it to protect herself, but it failed, and made the attacker pee'd off and went harder at her. She wont carry a gun, so thats out. I'm afraid of buying her a cheapo, that won't stop an attacker. I want her to carry one that will put someone down, the first time. I am completely ignorant in this subject. I've seen some that say 800,000 volt stun, then I see some that say 1 million volt stun, then 3 million volt stun. I'm sure the quality of the stun gun, has a lot to do with how well it functions. I just want something that wont fail. For example, I saw this at CTD: P.S. Products ZAP Light Flashlight and Stun Gun Then I saw this at Amazon: Guard Dog Security 3,900,000-Volt Stun Gun Flashlight I don't have a clue as to the quality of the product, or effectiveness. Can anyone help me with this? Thanks for any suggestions you can give! & to the mods, sorry if this question is in the wrong spot.
