My feet were getting really out of control. My heels were super callused, but in like a disgusting crumbly, flaky way, and I had dry skin peeling off all over the place. This thing worked wonders on shaving the dead skin off and smoothing my feet out. I use this after I shower and before I put on foot lotion. The skin comes off in a little compartment that collects the shavings, which is gross but also fascinating. For real, this thing gets it done. I love it.
