I had another type of these and my sister saw it and she fell in love with it! So I had to get another and all they had was this type which I like better than the one I had. With the two sizes it makes for a more polished look, plus some areas are a bit tender and the rougher side is too much. If you have rough heels or toes or anything in between I definitely recommend this. This is one tool that pedicure addicts need to have in their case. After a good scrubbing I feel like I've lost five pounds off each foot, it just feels so good. It's only a couple of bucks to make your feet happy so get one it is well worth it.

It doesn't shave off the callus, it just tears it up. Harsh. Ineffective.

Works better, costs less and lasts longer than the "egg." I swear by these things, but be careful... they can cause irritation if used too often.

It seems like if you applied strong pressure when using, it could snap. I think it works much better on dry heels. How about some tiny instructions like 'what side does what?' Overall it beats the hell out of sanders, which wear out.

It's pretty disgusting how the skin comes off like sand flakes, but hey it works. It removes build-up in between pedicures. Sturdy handle and two different sides- fine and coarse. Looks like a cheese grater! It works.

The first time I used it, I saw the dried skin on my heels fall off like powder flakes. It is simply magic! Excellent for dried heels and calluses!
