Review (5/5): Best callus remover I've found!
This is the best callus remover I've had yet. Start with the finer disk until you have learned how to use it. This is a very powerful unit. I've found that if I tap the area to be smoothed it doesn't overdo it or "burn". I can repeatedly tap the same area until I achieve the desired smoothness.
Keep in mind that calluses develop for a reason. They protect tender areas by growing thicker skin.....which means that as you remove the calluses, you can find your feet to walk over pebbles, hot sand etc.
