Review (1/5): Norelco blew it with the vac/trimmer/guard interface.  This thing is bad.
I'm very disappointed with this trimmer. The thing that made me buy it is the thing that makes this unusable. I speak of the vacuum. It does a good job at keeping the hair out of the sink, but its placement sets the trimmer so far back from the guard that using this trimmer on setting 2 (which is what I always used on my old Norelco T7500 to keep it nice and tight) is the equivalent of setting 7 or so (which is fairly long) on my old trimmer so I am unable to get a nice tight, trim look. Using it on a mustache is useless especially right underneath your nose. It is simply impossible to angle the trimmer in such a way as to trim the hair. I have attempted to use this trimmer twice and both times have had to result to pulling my very old T7500 out of the drawer and using it to get a decent trim.
Even setting this thing on the closest setting (#1) the trimmer still sets back waaaaay too far from the guard to be useful. If you contort you wrists and elbows you can get a fairly close trim on setting 1, but it is a giant pain to have to keep twisting and turning this trimmer around to achieve an even halfway decent trim. This thing is done. I'm shopping around for another brand.
I've been a Norelco user for over 10 years, but they blew it with this one!
