Review (5/5): Finally something that works for hubby's feet!
I've tried everything out there to reduce the thick callouses on my husband's feet. I pretty much gave up the cause a while back. When I saw this, I decided to give it a try. I couldn't believe the difference it made in just one use! You just have I be careful about how much pressure you apply and how high the speed is. Once you get the hang if it, it works amazingly!
For those with just "normal" callouses, I would suggest the fine discs. If you have those thick, rough callouses that put holes in your socks, the coarse discs are perfect.
