CallusFit® Electric Callus Remover
The CallusFit callus remover did a great job on my rough dry heels. Very easy to use out of the box. Unscrew the bottom to insert 4 AA batteries (not included). Turn on by turning the silver ring to the left and you're on your way to happy summer feet. Also comes with a cover, which comes in very handy when traveling. My only con is that it works off of 4 AA batteries; which could get expensive.
I received this product at a discount in exchange for my honest review.
