Title: Works for surface calluses but not all
Review: I had a couple of bad calluses from blisters I had gotten on the bottom of my feet and using a buffer wasn't getting rid of them so I decided to try this. It definitely works to get rid of dead skin but it did not help with my blister calluses. I ended up getting a callus shaver and that did the trick. This would be a good product for regular foot maintenance but for me didn't work for a more severe callus.
