Options include normal, sensitive and extra-sensitive. SkinGlide SkinGlide rings coated with thousands of tiny glass-like rounded spheres that reduce friction and surface resistance between the shaver and the skin. This gives the shaver a smooth, easy glide and helps protect against skin irritation. Skin Protection Technology This is designed to only cut hair - not skin. V-shaped blades guide the skin away from the blades for a close, smooth shave - even on three-day stubble. 5-Direction Flex Heads The shaver heads flex easily in five directions, gently following all the contours of the face and neck. Less pressure is needed to shave closely and skin stress is minimised. Aquatec Aquatec Wet and Dry seal means you can choose between a quick yet comfortable dry shave. Or you can shave wet—with gel or foam—even under the shower. Click-on Styler The Click-on beard styler has 5 length settings for beard styling, perfect stubble and pre-trimming. The cleansing brush is designed for deep, gentle cleansing together with your choice of cleanser. It's recommend to use the brush before shaving to get better results and less skin irritation. Good Battery Life The energy-efficient, powerful lithium-ion battery system gives you two convenient options: charge it for an hour for up to 50 minutes of shaving time, or do a quick charge for one full shave.
