Vacuum Trimmer Sucks,but in a good way [SEP] My wife always hated when I trimmed my beard because of all them little bitty hairs all over the sink. The T780 is not perfect but it does catch about 90% of those pesky little hairs. The trimmer is powerful and has no trouble with my dense beard. The batteries last a good long while between recharges.<br /><br />On the down side if you are a little aggressive with pressure as you trim it can slip to a shorter setting and it is a little heavier then some trimmers I have used in the past. All in all though it is a well designed trimmer that I enjoy using.
