For home use, I find this device well. It is easy to use and easy to handle. If one has a lot of course extremely cornea, then this device is not recommended rather to start with. Here a previous visit to a foot nurse would be more advisable. Therefore, I can not understand some recessions. Miracles can not be expected here. I lean forward, as I removed every morning in the shower the cornea with a pumice stone. Value for money is good.
