Question: If I use this on an attacker and they grab me in the process, will it shock me the same as them?
Document: Hope she never has to use it but in case she does, I am happy she has it in her car. Its sound is threatening.
If you want safety here it is! I am so happy that she has this with her, even though I hope she will never have to use it.
I cannot imagine being on the receiving end of this non-gun device. Get one for loved ones who will not use a gun. Up close and personal!
Don't buy it. The first time I had to use it, it failed on me. Also it was very hard to hold onto. I has an awkward grip and the switches were difficult to engage when holding the device. I returned it for a refund.
Activating this device will probably deter most thugs and criminals just by the loud current bolting through the prongs. I haven't had an opportunity to use it, which is good right? I trust that it will deliver a good blow, but cannot attest to that.I think the size of this device is a drawback for a typical pedestrian going for walks in the city or park - it's very bulky.
I am so glad that i purchased this. When it first arrived, everything was set up and working fine, after i put in the batteries of course. I then had my brother use it on me so that I knew it would work, and oh does it work!! Even though he only shocked me for a second the first time, i fell to the ground immediately! The second time he held it to me a bit longer, and I did not feel like moving at all!
I cannot say how effective this is, I bought it for my wife as a replacement for one that broke and she has had no reason to use it. It has a good strong spark like the old one I had so the spark and sound  would give one something to think about. What I do not like is the on and off switch as she caries it in her purse and seems it can easily be accidentally turned on, if something bumped or leaned against it that would turn it on.
I am not happy with the placement of the switch that you push to actually use it in a defensive way. A push button in the center of the unit would be much better. Also, I am not sure that it is working correctly. At first it worked as advertised, now even though the red light is bright indicating the batter is okay, I have to press the switch several times before it generates a &#34;spark&#34;.
This comes with a bulky clip on holster, which is probably not what you'll want to use if you are trying to conceal this. But if you take it out of the holster and place it in your bag or purse, then the cheap rocker on/off switch will bump into something and the unit will turn on and gradually drain the battery. This could have come with a depress in (clicky switch) to activate, press again to de-activate.
The 3 stars is for the switch. I believe the Stun Gun is very well made.
