FOG: Fog that is perfect for a short distance, the yellow cloud is highly visible and is a smokescreen that is true in 99% of cases everything up to a distance of 1m. Personally, I would prefer this. Since you do not have to aim accurately and in a panic this spray can apply an estimated well.
JET: has a recoverable beam, which can be used just circumstantial. However, this requires a little practice. One can also see here the yellow beam very good and correct in the desired direction. Still, it was a little more difficult this comparable work for me and my girlfriend with the FOG. With a little practice certainly no problem.
For pain:
I've gotten by rotating wind while practicing a "light load". I still have it noted on hours. To ward off a first attack or the conviction abort the attack it is enough definitely, because you can not really leave open the eyes at first glance, more it irritates skin and mucous membranes. Therefore only recommended
My favorite: FOG
