Review (5/5): Great product, works wonders.
I think the trick to this is not overdoing it the first time. You will see some great results from your first use, but after that if you continue to use it for a minute or two each day for a week or more you will have some incredibly smooth soft feet. I've never had such nice looking heels before. They were always hard and scaly looking. Be gentle, there really is no need to press down hard, just glide it along. If you keep up with it, you will have amazing results.
