The is a small but excellent device for home use. Delivered seven grinding pieces for plugging for the various tasks. For hand- and toenails there fine and coarse grinding wheels, protect the next-door by their shape the skin. The device features an integrated lamp, which is however covered by the conical shape of the nail grinding wheels; So for nail care you need an external light source. The device has no built-in battery; it must be used with the supplied AC adapter, so you have to work near an electrical outlet or use a Velängerungskabel. Personally, I get along well with them. I found the two speeds more than adequate. There are other devices where the speed is infinitely variable, but in my experience with the Beurer that would be only a theoretical advantage. I am very pleased with the Beurer MP 41. Everything is in a case beautifully packaged but quickly griffbar.
