I've used it once. kinda stupid though why. I sprayed axe bodyspray on my arm and lit it on fire, and usually when I do that it doesn't last long and it's easy to put out, buuuut this time it didn't go out and I threw myself to the ground and started rolling around. it didn't work right away, but it eventually went out. the only bad thing of the situation was the lingering smell of burnt arm hair. the good thing was that I had a smooth left arm for a little while
