Input:
I purchased the Microplane after reading all of the positive reviews pertaining to removing calluses of the feet. I have a box full of electric pedicare devises, scrappers like the EGG, and various lotions, etc. Some left my feet sore, but not this grater.

The first time I used it I was able to remove most of the calluses that I have been fighting for years. After about two weeks of use every 2m days or so my feet are now about 99% callus free. These are a little pricey, but worth every dime. Highly recommend! If I lost it I would buy another one. Also, very well made.
