My hairdresser uses the same machine since felt 20 years. Therefore, the right loud noise and the "scalp feeling" are very common. Nevertheless, I do not feel the sound and weight of the unit to be disturbing. The blades are excellent, the processing is great and looks very solid and with a little practice, the Bald is also shaved himself quickly.
Also, the scope of supply with oil, brush, 2 essays, and of course the device itself is in my view properly adjusted. For this price, I would even say sensational!
I went with the selection but also to the opinions given here and can confirm this only! A very good device at a top price!
