Since I was using an electric nail file from Promed already many years and was very happy, I decided again for a product of this company. Of course, the new product was not 100% the same. The Aufsteckköpfe today only have a metal pin, which you plug into an adapter and a parent must attach. At first I was a bit disappointed about that, but now I got used to it and think it's good. For my purposes, the accessory is too rich, so the storage is very huge, not so good to stow away in the bathroom. Therefore, I use my old case on and was doing just purely what I always need, it is just as pure. All in all I am very satisfied, the engine is powerful and works reliably. The cord to the power socket is also sufficiently long. The money for the equipment you soon out again, because you can save the professional foot and nail care.
