I picked this foot file up one day at Sallys when they had them on sale for $1. I really didn't expect it to work, but it did!! I honestly have the worst cracked feet and it took off all the dry skin on my heels. I was able to do my feet with it twice before I needed to toss it out... I believe someone whos feet aren't as bad as mine would get a lot more use out of it... but for a dollar you cant go wrong!
