It Works for What We Wanted It For [SEP] 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.<br /><br />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.
