Effect: target person goes immediately to the ground. Looks for about 30 minutes NOT. Eventually came his friends and had to call an ambulance. Police were also alerted and I got ne "display for grievous bodily harm" but it was dropped because of "self-defense".
In this situation, I was very grateful for the spray. It's incredibly effective, quick and used also for women or more anxious people very helpful.
But since it is very aggressive, I would really advise you to use only in animals, unless a life is in immediate danger.
In addition, there are often better, smarter and more alternative ways to prevent a confrontation of this kind as to use this hochaggresive stuff.
Wenns push comes to shove it acts but in animals as in humans.
