The Best!!!

I've been wowed by every product I've tried from this line, but this thing here???? Nothing like it. Don't even waste your time on foot files. I have...wait I HAD thick callouses on the bottom of my feet, and they've been obliterated...gone. I'm speechless.

Rough foot solution!

I bought The Gratest and LOVE it!! I have had rough callused feet since I was a teenager and I've gotten regular pedicures for years. A few days after a pedicure, my feet are back to being rough. Using this tool has been a lifesaver! I can’t believe how smooth my feet feel. I used it on my husband’s feet as well and he was very impressed. I highly recommend this for anyone who has rough and callused feet. And what a great deal!
