vacuum trimmer sucksbut 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 is not perfect but it does catch about 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 rechargeson 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
