I just had to know and have me leave this Pfefferpray spray in the face. I wanted to know if it does what in an emergency. Now the self-test: a friend of mine has Ca. 1-2 meters sprayed me with eyes wide open in the face and you do not even have to aim directly, as it spreads. I was just as good as blind, could not open my eyes. My eyes and my face have so blatantly fired. Only after about 10 minutes I was reasonably open my eyes slowly, but I was still out of action. All my nose was clogged and could breathe only through your mouth. After about 20 minutes I was back to normal view, but still burning with.
Conclusion: strong buy recommendation. For the 2.50 pc. It can in emergencies, save lives. And not test yourself, except you're into pain or are you a little disturbed in mind as I :)
