This is a great little item! The flashlight is bright, the siren sounds silly but is loud, and it really packs a punch! The safety disable pin is a great touch. It is hefty enough to do some damage if you have to resort to hitting someone with it, but not so heavy as to become uncomfortable while carrying it. We are very pleased with our purchase!
I bought this because I was looking for a nonlethal way to break up dog fights after my dog was attacked by a small pack. After a little research I came upon this product. It has a flashlight which is nothing special; a siren that will attract some attention if anybody is close enough; most importantly, it has a a zapper which will scare anybody with half a brain. My dog didn't particularly react to the noise of the zapper or the size of the lightning bolt but a human would. There is no doubt in my mind..
This product does what it says ... which is the most important thing! Having said that, this self-defense unit is cheaply made (in China). Although it may be advertized to sub as a baton (striking weapon), there's not enough heft in this plastic tube to knock a cat out. Yeah, I'll carry it in my vehicle, but doesn't quite give me the confidence I was hoping for.
