The Two Axis Flex™ foils of this system closely follow the contours of your face, while an inner cutter gets the long hairs. The extendable Rizer™ gets the tight spots of your face (under your nose, close to your ears). The rubberized ergonomic grip looks great and provides the perfect hold. The powerful battery gives a full week of cordless shaving on a single one-hour charge. The pop-up trimmer takes care of your moustache and sideburns and the smart charger automatically coverts to international voltage.
