Wow--this thing really works! [SEP] The Emjoi Micro-Pedi does everything it says it will:  if your heels are super-dry, it might take a while to get them to baby-softness, but after the initial use, all you have to do to maintain is to use the device every several days, and just a few passes over each heel should do it.  I have used it numerous times since I bought it and still have not had to replace the original head. Highly recommended!
