This is now the third pedicure / manicure device that I have bought over the years and by far the best! The equipment and the extensive accessories is self-explanatory, a manual is not necessary. The handpiece is not hot despite long operation, it will not again warm, super! Can be reduced by 25,000 revolutions which simply rotate through the switch as needed, you are supplied more than adequate. Practically I find the simple changing the revolutions of right to left operation, which indeed, when the handpiece with the left hand is used, is absolutely necessary. The grinding wheels are very well stocked and of very good quality, for every requirement the appropriate grinding body is. Abrasive and goat hair brushes to polish the nails can be, when you need to buy for very little money to do so. The value for money is great, the unit gets an absolute buy recommendation! The delivery was very quick, the contact with the seller is professional and very friendly, this was certainly not the last that I bought at InstrumenteNRW ;-)!
