Benefits:
- Fits comfortably in your hand
- Light
- Relatively quiet and smooth
- Cuts very pleasant (ie without any tearing of hair, what I experienced already in other devices)
- Cuts and pain without comb attachment and blood-free (tested on neck hair, ear area and the hairline)
- Seems to have actually caught all the hair, at least have me after looking in the mirror no "resistance fighters" noticed
- Easy to clean (washable)
Disadvantages (or: bleating at a high level):
- The comb attachment wobbles in larger settings a little and gives the impression that you should be treated with care;)
- The BT7050 want to be re-oiled after each use.
For quality of the built-in battery, I can certainly write anything yet, but do not worry me in this regard. At least he can recharge quickly.
If the device also in a few years still works nearly as good as my first test, is by far the best of brown hair trimmer, I've ever had.
