Review (4/5): Even Brad Pitt uses one of these...
...doesn't he? (How else does he maintain such an even, three-day growth for months at a time?)
I have the T770 model depicted above, so I've been a happy user for nearly two years. In his review, Reuben gives good tips on the use of this trimmer: take your time when you use it and clean it out after every use. The first results in even trimming; the second allows the vacuum to work best. Yes, a few hairs will show up in the sink, but with one swipe with a damp tissue they're gone. The adjustable comb trims beard, mustache, goatee, etc., to any length a user might want. In addition to the trimmer, the mustache and sideburn clipper gives a precise and neat edge; to use it, just remove the comb.
Taking the T770 apart to clean the blades is easy; getting it back together properly requires careful assembly in good lighting and some patience. I wish Norelco would simplify the re-assembly mechanisms and process. But even that, since I have now mastered it, does not truly lessen my liking of this product. Nor does its charging time; the T770 holds its charge for around two months (and I use the trimmer 2-3 times a week).
Should I drop and break this trimmer, as I did with a previously owned Remington, I will replace it with another Norelco. It's been great to have said good-bye to scissors.
