For weeks in use in the family circle for pedicures. Even with problematic nails comes Maniquick MQ 251 cope very well. The unit is quiet and the speed is adjustable. Lots of accessories, most of it we do not need (yet). What I do not like. The company advertises gift (personal scale) when you write your own review. I can live without the gift. I leave myself happy on customer reviews and find no good, that through such actions thank the opinion of the writer may be affected. There are plenty of advertising and selling reviews. The device I can definitely recommend it.
