I bought this unit because of its functionality. This device has a head with 2 different rasps. The blue is a very rough and gray very fine grater, so that you can remove the cornea easily and get your feet well until smooth. The device has a 2 stage switch for fast and slow running, which allows you to edit toes well. The battery in this device stops in front of a long time and is fast with the supplied charger ready for use again. The handling of Hornhautentferners is possible in the battery as well as in network operations. I can really recommend this unit to anyone who wants to have his feet clean and smooth. :-)
