I have the trimmer for about 1 year and 3-4 times / month in use.
1) The build quality is perfectly fine. Nothing is loose or has air. Really good.
2.) About the Battery I can not say anything. I have the device always at the net.
3.) Especially bad I find the cutting precision of the device.
The problem I see in the fact that is the "length distance comb" for beards too coarse.
He manages just not evenly raise the whiskers and uniformly to cut long.
From my perspective, would only help here to make much finer "distance comb," said he before cutting really raises the hair.
I find that strange, to the difference in production can only lie in cents range.
4) The device can be opened and rinse under water. It's good.
5.) The design is quite nice, but who needs nice design, when the cutting is only mediocre?
Conclusion: I would not buy the device due to lack of precision again. The euphoric 5 star reviews I can not understand.
I'm just "German" and if I set 5mm, then I want to 5mm have no chance and drive results for the third time over his face.
I have no alternative purchase proposal, but who wants more precision, should particularly watch for other devices the length distance comb and see how this raises the hair.
