The Remington R4002 is a rotary electric shaver from the R4 Style Series designed for dry shaving. It features three shaving heads equipped with Dual Track Blades to provide maximum coverage across the skin, while the pivoting neck and flexing blades allow the device to follow the natural contours of your face for a closer feel. For detailed grooming, this black shaver includes a pop-up trimmer with ComfortTrim blades, which helps you maintain sideburns and clean up your jawline. You can also achieve a specific look using the included 3-Day Stubble Styler guard. The device is powered by an internal Ni-Mh battery that offers up to 40 minutes of cordless use after a 16-hour charge, though it can also be operated directly from the mains. A simple slider control manages the operation, and a charging indicator light lets you know when the battery is replenishing. The set comes with a cleaning brush to keep the blades in good condition.
