Review (4/5): It sucks. And that's a good thing!
I owned another Norelco beard trimmer with a vacuum in it ... until my wife broke it by knocking it off the shelf. But now I'm glad she did. On the old one, the vacuum was fairly useless because just as much hair ended up in the sink and all over the blade as in the catcher bin. Maybe more.
But the T980 Turbo (and don't all guys love stuff with "Turbo" in the description?) does the job. Yes, I know it has two settings: Turbo on and Turbo off. But I see no reason to use it with Turbo off because then it's just like the old underpowered version. But with Turbo on it collects nearly all those little hairs. (Some get away, but many fewer.)
Some people say that the Turbo is too loud, which is why they offer an option I suppose, but in our house the bathroom is far enough away and well-insulated enough that no one can hear it running full blast.
One caveat: It's better to trim the beard dry not wet. Remember to trim it before you get in the shower because when the hair is wet the vacuum still has trouble collecting the hairs, even on Turbo. Plus showering washes any remaining trimmings away. Yes, this may be self-evident to some of you, but I hadn't thought of it before. Keep in mind I'm doing this before morning coffee.
So no more little hairs all over my daughter after daddy kisses and snuggles her. I like the T980 trimmer.
