Review (2/5): Can't recommend
I had a Norelco trimmer for a number of years and was very happy with it. The T780 works OK and I really like the vacuum concept.
What I DON'T like is, the adjustment ring does not come with any marking to show the relative depth of cut. Thus, I'm merely guessing from one cut to the next.
Also note (and this is not part of my rating), when you use Super Saver Shipping, they sit on the order for a week before they ship, so don't select it if you're in a hurry.
