Have the machine for almost a year. Just because the price is so low, it is just about ok. Because unfortunately there are some strong deficiencies mentioned. 1. The essay is a disaster. He is flexible and so it may be that you cut on uneven places deeper than intended, because the essay tips can bend away to the side. He is also not very stable. After less than a year a plastic piece is broken off. Now he is infinitely adjustable !!
2. The battery life has been greatly reduced. A complete haircut on battery power impossible.
3. The cutting head is already very worn. It can indeed be replaced but for the price is too high.
Everything only suitable in particular for rare use.
