The Norelco Shaver 5150 adds speed and comfort to your morning routine with a fast, MultiPrecision blade system. It shaves with fewer passes for more comfortable skin. The heads flex in five different directions to ensure close skin contact for a faster, closer shave, even on the neck and jaw line. The included SmartClick nose and ear trimmer attachment comfortably trims unwanted nose and ear hair. Also included is the SmartClick precision trimmer, which is perfect for sideburns and moustaches. For best results, replace shaving head every 12 months and use replacement head SH50.
