Review (2/5): You could get the same results or better with a good pumice stone
This item will slightly smooth rough skin, but does little more. You could get the same results or better with a good pumice stone. It is battery powered, takes 2 AA, so it does not have a lot of power to it. I am disappointed and sadly would not recommend this product, it just is not capable of doing what I expected with this product and I don't see it being able to remove any callus.
I have received this item at a reduced rate in exchange for an honest review and I hope that others find this helpful- I don't think its worth the money.
