Review (1/5): adjustment doesn't work
It seems fine for a battery operated trimmer, EXCEPT! The trimmer doesn't stay at the setting you want. So, I used it for the first time this AM, put the setting on 5 or 6, but after a few strokes on the beard, it reset itself to the lowest setting. So, one spot on my beard is now down to a stubble. So, I have to go ahead and shave the rest of my beard that short. I tested it over and over, and slight pressure resets the length mechanism.
Long and short, the thing doesn't work. I'm returning it.
