I would hate to use something formulated for bears on a person and then have them get a good lawer, even if it was less potent I could imagine how it would get twisted around in court.
Pepper sprays are measured in SHU's (Scoville Heat Units) here is a comparison for you:
Green Pepper = 0 SHU's
Jalapeno Pepper = 14,000 SHU's
Habenero Pepper = 40,000 SHU's
Fox Labs 5.3 Pepper Spray = 5.3 Million SHU's
We use the Fox Labs where I work, just be aware that most manufacturers will make multiple sprays with different potencies. Read the label and do your homework before you trust your life to it.
I also had to get sprayed in training and it was truly terrible, it will put most people out of commission. That being said, I have seen(first hand) where it did not work on someone having a violent psychotic episode.
You may want to ask about results from people who have actually USED it, as opposed to just "what kind do you carry?" Results are more important than the fact that some guy was told that this brand is best so thats what he carries.
+5.3 million SHU's to Fox Labs.
