It's a great router. I had a manicure yesterday and just enjoyed it. Handle doesn't vibrate, revolutions are smooth. When removing the length of the nail plate, the handle doesn't short out, the movement is smooth, doesn't get stuck anywhere. In general, the purchase satisfied. I hope it will last for a few years. The only thing bad read the description, the machine works only from the pedal. ???? When I do my own manicure - it is not convenient. And the clients work on the pedal. Oh well.
