Review (4/5): Great, but use before showering
I bought this trimmer after my old Norelco stopped charging. For the record, I maintain a full beard with this. Overall, I am satisfied with the product, but there are some caveats.
Vacuum: Like me, you may be interested in the included vacuum, rather than getting hair all over the place. It works pretty well for this! I'd say about 90% of the hair is trapped in the canister, about 3% on the sink, and about 7% left in my beard. For this reason, I recommend using the trimmer before you shower. Otherwise, you will get little hairs all over your shirt during the day. If you only have a goatee or similar, it may not be quite as bad. It's not much hair, but the little vacuum can't solve everything.
Noise: The noise level is loud, but not really any noisier than an electric toothbrush. To me, it's really no big deal. With the bathroom door closed, you can only hear it when close to the door anyway. I even run it in turbo mode most of the time, and still don't have an issue with this. Of course it would be great if it were completely silent, but really it's not that bad.
Trimming: Like all Norelcos, it does a great job trimming. The included adapter(s) handle just about everything I could imagine needing. I am a hairy guy, and have not felt any pulling or ripping of the hairs, just a clean trim.
Power: I typically get several weeks worth of trimming (every 2-3 days) on a single charge. To maintain the battery, always ensure you fully drain it before recharging. Using turbo mode drains it slightly more quickly. I can go a whole vacation without needing to recharge, which is nice, but the included travel bag is handy just in case.
So, overall I'd give it 4.5 stars, only because of the leftover hairs. It would be nice to have a slightly more powerful vacuum, but I realize it's difficult to get the hairs that are trapped in a beard. I love the trimmer, and have not seen anything else out there that would beat it.
