Good, copes with its functions, on the first day I did a manicure and pedicure. There is an instruction, but everything is clear even without it, it is easy to use. Cutters immediately ordered new, those that are not suitable. Whoever writes that the cutter clamp lock does not work, first check if the tip of the handle is unscrewed, it must be completely screwed in, I also accidentally unscrewed it and could not get the cutter)
