If you use the Remington Ultimate Series R7 XR1530, you are assured of a smooth result thanks to the flexible shaving head. The shaving head moves in 4 directions and effortlessly follows the contours of your face. And you shave without the risk of skin irritation, because this shaver has LiftLogic technology. This means that the first shaving foil lifts the hairs, and the second shaving foil shaves the hairs close to the skin. You shave dry, with foam or in the shower. After 50 minutes of use, the battery is empty and you place the shaver in the charger, the 3 phase LED charging indicator shows when the battery is fully charged. Charging takes 240 minutes.
