Very pleasant is the adjustment of length on a cog. It can be operated with or without attachment. In the quite short hair, the hair cutter has pretty well done, but also differed not particularly of older models, which come from a similar price range. Here remains to be seen whether the blade technology can score in the long-term test.
For slightly longer and quite thick hair but also came the Power hair trimmer to its limits and could not convince. Here you should really make sure that the intersection of a length of 0.5 to 23 mm is. The device is therefore more suitable for fine work. Who wears the hair a bit now and then longer and the cutting forgets should rather resort to another device.
Another positive factor is still the long battery life of 2 hours worth mentioning. Of course, one is not two hours a haircut, but you have not even connect the device again after each cut. So you can also make little beauty in between work.
Conclusion: A reasonable price range for the device that works rather fine.
