Review (5/5): Does what it's intended to do
I've owned this trimmer for over a month, and have no problems with it. It does what it's meant to do: trims my beard. I had an older Norelco trimmer prior to owning this one, which did not have the vacuum functionality. The vacuum does pick up most of the hair, but when I grow my beard for a week, some of it does end up in the sink. I do not mind this, as it would be nearly impossible for something of this size to get all the hair. What I like is that it's kept to a minimum. One annoyance that I have is the plastic slide in front of the blade (which aids in funneling the hair into the vacuum) sometimes disrupts longer hair from getting cut. So I tend to do a bit of back and forth with longer areas to trim them properly. Also, I do not believe you cannot trim while it's charging. Not a bit deal though.
All in all, this is a fine trimmer, and I would recommend it to my friends.
