I own this product now for almost 1.5 years and use it almost every week for a haircut on the head. I can not complain, the performance is very good, it is enough twice to thoroughly go through the hair over it and it will stop nothing. The device also does not stop because jam too much hair or the like. The only drawback: I would imagine that there are lighter equipment. The fine workmanship, easy operation, reliable performance, and that the device previously had no failures do it for me but made up for it. I do not see why I should be a point deduction.
