Philips Norelco Shaver 6400 (formerly SensoTouch 2D) combines Gyroflex 2D and SkinGuide for a close, comfortable wet or dry shave. It has a smooth flat surface with rounded edges to provide an extra-close shave with less irritation. The Lithium-ion rechargeable battery delivers 40 minutes of cordless shaving after a 1 hour charge. A 3 minute quick-charge provides enough power for one cordless shave. For best results, replace with RQ11 replacement heads every 12 months. Packaging includes: electric shaver, charging stand, click-on precision trimmer head, protective cap, power cord and cleaning brush.
