Review (4/5): It Works for What We Wanted It For
Husband grew a beard the moment he was put on blood thinners, and he has it trimmed once a month, but sometimes that's not enough. When it gets too long he tends to look like Grizzly Adams. I would keep it tamed with scissor trims, but this works much better; he can do the trim himself, and also trim his cheeks and mustache. We haven't tried it on trimming the hair at the back of his neck.
He does not like that it is only USB and you have to buy a wall plug adapter to charge it. I guess they figure most people have them now, but it should come with one. That's just being cheap.
