Works well for me
I bought this to replace another Norelco beard trimmer with a dead battery.  The T980 works well for me, using the shortest setting (3 day stubble, I think).  The vacuum feature is good, keeps the mess to a minimum, but not perfect.  It holds a charge for a few weeks (based on using it 2 x week, 5 min each), recharges quickly, works with or without the cord.  My only complaint is the size of the trimmer head.  It's pretty large, and the blades are set back about 1/2 inch from the edge, so it's hard to get close in some areas (nose and ears).
