Philips QT4001 Trimmer, was my first choice.As I didnt know much about other trimmers. It worked pretty well but , never cut zero. So I was not much satisfied with it. Comparatively, its not better than philips trimmer cutting extreme zero.
Atleast philips trimmer , cutting extreme zero excel, which makes ur face feel clean, clear and fresh. I would suggest whosoever is using philips Qt4001 trimmer , kindly plzz switch to some other trimmer which cuts zero and makes ur face feel real good.
