Took the heel calluses down to smooth skin easily and quickly. Sure beats the Dremmel tool with sandpaper that I've been using for years. NO skin burn either, which was very pleasant. This item will pay for itself in savings on socks alone. I would highly recommend this product to everyone. Very happy with this purchase!
