Query: A real disappointment from Norelco...

Well, even though this item had mixed reviews, I tried it anyway. While the trimmer does work, the promise of no mess with a built in vacuum that actually works is not what you get. The trimmer captures only a portion of the hair that is cut -- and not a particularly impressive portion at that. If you follow the instructions and start with the higher setting and work your way down, it does work better -- but even then, the trimmer only captures about 75% of the trimmings -- which of course results in the rest falling into the sink, onto your shirt, or onto whatever is below. It is possible that this trimmer works better for some types of beards than others, but for me, this is a throw away purchase (literally). Back to my old trimmer.
