Bests & Worsts Reviews from Amazon

I've been using this stuff for about a decade or so, and I think I've bought three or maybe four of these rocks in that time span. They last forever. Only thing is you have to have freshly washed pits or it doesn't work. If you use it on skin where the funk has already started it seems to transfer onto the rock itself, which upon further applications will just make you even funkier. But if you do get some funk on the rock, just wash it and it's all good. Sometimes i put a drop or two of essential oil on it to give a little scent?
