T780 is okay.
This is about an average trimmer. The previous one I had was a Norelco and it worked better. One problem is that if you break the comb part (which is easy to do and which I did with the old one) then you have a time finding a replacement part and when you do it will cost over $15.00. Those of you who have trouble with it vacuuming properly may be holding it so that your hand is covering the vent holes in the handle. Of course this is going to make it hard to create the proper suction and air exhaust to do the vacuuming. The door for the collection chamber is a pretty flimsy device. The older one I had, had a removable chamber that was much easier to empty.
