not as good as the trimmer on my norelco shaver [SEP] i have had a norelco series shaver with a trimmer for awhile when i grew a beard i bought this unit based on the reviews i read here at amazon it is true that because of the vacuum there is less hair in the sink but the quality of its trimming is far below that on my norelco shaver if i would known then what i know now i would have passed on this item it may be good for those who do not have a norelco shaver with the trimming feature and do not want to pay a hundred dollars or more for such a shaver but for those who have such a shaver this product is at best superfluousjanuary s not even a year later and it has broken already i am not a happy camper
