It's a very effective and impressive pedicure tool and does the job with calluses. But you must be careful not to overdo it, and I suggest going over with a finer footfile.

Works perfectly, it is very gentle. Better than anything i ever used!

Best one I have ever used! My feet are now so smooth and soft :)

This is a really great product - and I found that it was still quite gentle - I didn't manage to hurt myself (which is frankly a miracle). I really love that there's a plastic cover that you can put on the back to catch the dead skin so that you don't have to worry about making a mess! 

I love that the whole material is robust and doesn’t get bad once in the shower. It removes the dead skin super fast and leaves my feet soft.
