Great product at a great price.
I had reservations about purchasing a rock with a rope that's supposed to take callouses off. I've read reviews where they crumble or break into dust, and with the price I thought I'd be ripped off. However, it seems in no way breakable! I'll update if it breaks or something, but after a month, so far, so good. I suggest soaking your feet for at least 5-10 minutes, preferably with a drop of baby or essential oil before scrubbing. When I say scrubbing, I mean rubbing with circular motions. It should never, ever hurt! Follow it up with some good foot creams and soft socks. Just don't overdo it! I've used it 5 times but once a week is probably all you need.
