Review (5/5): OMG.  Buy. This.
So satisfied with this purchase. I was able to eradicate my callouses in 10 minutes for less money than it took to get a pedicure that didn’t even come close to achieving the same results. I wear heals every day so I had several rock hard callouses on the balls of my feet and under the pinky toe. I mean rock hard. They were smooth but they were hard to the touch and after my last pedicure I had resigned myself to the fact that I was just going to have to either buy a razor and try to carefully remove them (eek) or learn to live with them. I looked at wart removing cream as I understand that can help but I figured I was in for a long haul to get them to the point where they were maybe slightly improved and that I’d probably have a lot of maintenance. Then I found this. 10 minutes later - no chemicals, nor razor blades and possible infections and also...no callouses. My feet are BRAND NEW. I did it a second night, even better. Baby feet. I figure I hit these once a week for like a minute and I’ll be good. I’ll never be without this little gem of a beauty tool again. Seriously, don’t think, just buy it. So worth the money.
