Experience the world's closest electric shave and uncompromised skin comfort with Philips Norelco S9000 Prestige. NanoTech precision blades are strengthened with nano particles and have extra strong and long-lasting sharp edges to cut hair with the highest precision for the closest results. Our excellent skin comfort system enables you to effortlessly get a highly efficient shave, even on a longer (up to 7-day) beard. Its new wider, rounder openings catch more hair per pass, resulting in a difference you can feel. The BeardAdapt Sensor checks hair density 15 times per second and automatically adapts the shaver to your hair. Choose between 3 modes to customize your shave: 1) Sensitive - for a gentle, thorough shave. 2) Normal - for a thorough, everyday shave. 3) Fast - for a quick shave that saves you time. Get a convenient dry shave or a more refreshing wet shave with gel or foam - even in the shower. Finish your look with the skin-friendly click-on precision trimmer. It is ideal for maintaining your mustache and trimming your sideburns. The premium travel case protects the shaver as well as its accessories. Its thoughtful design matches the timeless elegance of the shaver. Shave longer with every charge, thanks to a powerful and long-lasting Lithium-ion battery.
