Safe and effective
I had cracked calluses on both feet but read a bunch of horror reviews for those foot scrubbers that are basically cheese graters so I purchased this.  I'm glad I did, as this is a safer alternative.  It made my feet baby smooth and took care of the calluses.  I used it while still in the tub after a shower so my feet were pruney.  Lots of skin came off but unlike the cheese grater-type foot files, it doesn't come off all at once.  That's what makes it safer.  I use it monthly for maintenance now.  Nice handle, it looks and feels like a quality product.  I paid $10 and it was well worth it. The product will not rust.
