Review (1/5): Beard and mustache trimmer totally useless
The basic three-head razor function is not bad, but the beard and mustache trimmer does not cut at all: the effect is like hacking away at one's face with a butter knife, occasionally grabbing a strand of hair sufficiently to pull it out by the root but otherwise having no useful effect at all.
I regret that I did not return during the window, but I bought it for travel and did not realize soon enough how bad it was.
