Review (1/5): Does not remove callus's
As the title says, this machine does not remove callus's. It couldn't even remove normal dead skin much less a callus. The tool worked except that if you press down too hard the motor slows and the rotating disc slows down quite a lot. I understand this is probably to help prevent injury but it makes things a lot slower and annoying. I tried using a higher speed and the disc did get a little hotter so I imagine if you're not careful you could get burned, it just goes too fast (which doesn't make a difference in removing dead skin btw because I tried the lowest speed and a very high speed).
I only have 1 callus and it's not a bad one but then the skin on the rest of my feet just needs to be filed down a little bit and I give myself pedicures all the time, I usually use tweezerman files and I can see if it's working because when you file off dead skin it turns into a white powder sort of. Using this product, hardly any dead skin was taken off at all, just a tiny bit. It wasn't pretty much polishing the skin instead of removing the build up.
I've already contacted amazon to return this item...it is NOT worth 50 bucks. In my experience it doesn't work at all & I would not recommend buying it. I guess I will stick with regular filling and elbow grease.
