The ped - egg product worked pretty well on my feet as well as my mother and friends' feet. It really got a lot of the dry skin off just like it said it would. I do, however, think that ten dollars is a little pricey to pay for something that is basically a cheese grater. Also, you cannot use it right after you get out of the shower or it will kind of make your skin bumpy. It doesn't hurt if you do that, it just does not make the skin smooth like it does if you use it when your feetsies have been dry for a while. Also, the replacement cartridges also purchsed at walgreens would not fit tightly into the old ped - egg, which was quite dissapointing because it kept just falling out. Overall, I was pretty satisfied so I gave it high marks except in the durability and quality for the misfitting replacement cartridges.
