The Panasonic ES8243 (or Arc IV) is a top of the line cordless electric shaver which uses Panasonic's most advanced shaver technology. This is a wet or dry shaver, which allows it to be used in or out of the shower, with or without shaving foam. However, the most notable technology lies in the floating quadruple arc foil shaving head. These use super sharp 30 degree blades and feature an ultra thin three dimensional hole patterned stainless steel foil to ensure the closest shave possible. The pop-up trimmer allows trimming and contouring of beards, moustaches and side-burns. The rechargeable lithium battery fully charges in 1 hour to provide approximately 14 shaves. There is also a 5-minute quick charge for one shave if needed. The motor runs at 13,000 RPM, but increases to 17,000 RPM when you hold the ON/OFF button, which enters it into the turbo cleaning mode for easy cleaning, which is as simple as running under the tap. The LCD display indicates when it is time to clean or recharge your shaver. Included accessories are travel pouc and AC recharger. Available in blue (as the ES8243A) or in black (as the ES8243K).
