Review (5/5): Great trimmer
I purchased this trimmer in March 2009 to replace an older Norelco T770 model trimmer whose battery was dying. I have been using the T980 regularly (roughly weekly) since then and am very happy with it. The T980 is a nice upgrade. It looks and feels sturdier than the older T770.
I used to have trouble with the older model T770; the dial that regulates how close a trim you get would slip a notch. I haven't had that issue with the new trimmer at all.
The vacuum works well and the vacuum compartment is easy to empty and clean. To clean out the drive compartment you must still remove the trimmer head and use the included brush.
I can't comment on the Turbo setting because I haven't really used that; for me it works just fine at the normal setting. Battery life so far has been good, noticeably better than the older model even when it was new. So far, with my weekly usage I've only had to do 2 charges since the initial one.
