Slow Process but Works
While the Emjoi Micro-Pedi POWER does work, it does take time.  I ordered a package of the most coarse rollers with the device.  It does smooth the heels but would need to be used daily to keep up really rough or dry heels.  I did not find that it made as much of a mess as some stated, but I sat on the bathroom counter with my feet over the since and paper towels and did not get any dust outside that area.
