This is a 5 star product through and through. I’m a barefoot kind of person who does not take care of my feet so my heels have been awful for the last 15 years. I’ve used regular foot files and even the tool that shaves off the dead skin - use of these tools together helped but never seemed to help heal those DEEP cracks in my one heal (wish I had a pic because no pics on here come close to how bad mine were). I’ve had this file for not even two months and my heels are 90% healed. Literally, one more week, one more file and signs of anything remotely close to dryness or cracking will be entirely gone. Buy this file. Not only is the price right, but it works! Already bought another for my mom. Amazing!!
