I've always heard of pepper spray, seen it used in the movies, always thought it was something for women to use on purse snatchers. I always had the impression that it was a pretty weak self-defense weapon. I figured it would be an experience similar to getting sand thrown in your eyes, etc. I figured it would hurt, and give you a few extra seconds to get away, but otherwise do little besides piss somebody off even more.
However, I just got through watching 4 or 5 youtube videos demonstrating this stuff. These people can't see at all, can't open their eyes. THey are in severe pain, and it seems to get worse with every second that goes by. These people are totally incapacitated and, I dare say, might even be more effective than a shot from a gun at stopping somebody.
I'm definitely going to buy some of this for me and my family.
