Review (5/5): Works great, so little cleanup
I've owned a few trimmers over the few years, and none had a built in vacuum. After losing the power cord to my last one, I went shopping and found this gem. The vacuum intrigued me -- would it really be worth the extra $20-25 over a standard trimmer? One word: Yes.
I'd always put off shaving my beard due to the necessity of cleaning up afterwards. I just trimmed my beard, which had grown out over the past two weeks, and amazingly, the sink below me only had a few pieces of hair in it. That is totally acceptable in my book, and with this I'll be keeping my beard trimmed often because cleanup isn't a hassle anymore.
Highly recommended. I can't speak for longevity, except that the trimmer I'm replacing was a Norelco that I bought almost two years ago, and it's still running (albeit it just died because I can't charge it anymore).
