The Philips SP9871/13 S9000 Prestige offers the best shave, with ultimate closeness and skin comfort, even on a seven-day beard. With Aquatec Wet & Dry, you can opt for a comfortable dry shave, or you can shave wet with gel or foam, even under the shower. The SH91 NanoTech precision blades give you an exceptionally close shave. The shaver can be easily cleaned. Simply flip open the shaver heads and rinse under running water. Not only will your shave be more comfortable, it will also be more efficient, even on a longer beard. The BeardAdapt Sensor checks hair density 15 times per second and automatically adapts the shaver to your hair. The SH91 blades catch more hair per pass, while the multi-direction ContourDetect heads follow every contour of your face, catching even difficult hairs. The S9000 Prestige allows you to charge your shaver wirelessly by simply placing it on the Qi charging pad. This Premium shaver is made in Holland and comes with a 2 year warranty.
