my worst experience was a hot one. i was bow elk hunting and had encounter with a bear so I took the safety cap off of my bear pause or pepper spray some call it. Anyways the bear was just bluffing me but i lost the safety cap for the spray in the excitement. The next day i was walking throught the bush and one of my gloves fell off. The spray was clipped onto my belt and when i bent over to pick up my glove the nozzle went off and spray shot all up my back and dripped onto my rump. i though nothing of it and I kept on hiking. well 30 minutes later my clothes were all off and i was bathing in a slough. Washed that spray off the best i could and then built a fire. If u have every applied linament to sore muscles well X15 and that' s how hot that spray was. My body has nver felt heat like that. no wonder it does such a good job on bears.
