I bought 2 months ago my machine; At first I was a little unsure as to whether the very moving unstable acting essay is to be adapted to the head shape. However, the bottom line this feature is neither necessary, nor does it interfere. Since then, however, proves to be stable in handling, there is no reason not to buy the hair trimmer. The device has to be set as a minimal cutting stage only 3 mm, which I actually a bit too much, I prefer from 1 to 1.5 mm hair length. Stages in general: 3, 6, 9, 12, 15, 18 and 21 mm. I cut my hair now without attachment, goes, then is approximately 0.5 mm hair length. Power of the engine is good, does not have problems even in battery mode omit several cutting steps and cut away all the same. (Battery is still new but it is possible ...) Overall it cuts amazingly clean, but unfortunately no voltage adjustment for foreign missions. Because the device is not the case "brewing equipment" üblche securing the cutting stage has (if you have to remove the attachment in order to forestall any hair clogging), one must be careful here not to cut back on even more than what you had in mind actually. Overall: good performance in good to acceptable price and brand quality, has, however, not relocating cutting fuse, only 3 mm blade spacing and no world power adjustment.
