This revolutionary system captures more hair in fewer strokes, even problem hairs, leaving you with the closest shave ever. The pulsing sonic head stimulates tiny vibrations on the skin to loosen and raise hairs. The cross-cutting technology creates an opposing directional movement between the shaving foils and the cutting blades, delivering a fast, thorough and comfortable shave. A contour following system automatically adapts to the shape of your face, flexing and pivoting to ensure maximum facial conformity. Shaver comes equipped with the Clean&Renew? base, which automatically cleans, lubricates, dries, and charges the shaver at the touch of a button. Shaver has a watertight seal so it can be washed under tap water if the base is left at home while traveling. System can be used corded or charged, and also features a visual information LCD display and an energy-efficient electrical adapter.
