I use them. I think they work really well. The one caveat though, is that once you get smelly, you have to wash again before you can use the stone. It *prevents* odor, it doesn't remove it or cover it up. That's fine, I usually shower every other day, so on the days I shower, I use the stone and I'm good for 24 hours, and then the next day I dab a lil lavender EO on.
