Braun Shaver Series 5 570cc Review

In the quest for a truly thorough shave, new Series 5 from Braun leaves no stone unturned. With a unique Power Comb that lifts and cuts hairs growing flat against the skin that otherwise would be missed. Series 5 provides smoothness as standard. Together with a slim, contour-adapting head that slides effortlessly into hard-to-reach areas and hand-friendly ergonomics for total control all over the face, Series 5 delivers a thorough shave all over the face, with no missed hairs. Sleek and sophisticated, Series 5 exists to give you a thoroughly smooth shave, with a combination of technical superiority and design excellence. Poised beneath Braun’s microscopically thin Smart Foil, a unique Power Comb works in harmony with the hand’s natural up-and-down linear movement to trap and cuts hairs that grow flat against the skin. They sure won’t be missed. Grip-friendly ergonomics just cry out for a firm hand, allowing Series 5′s slim, contour-adapting head to produce a thorough shave no matter what the facial terrain throws at it. Mean and clean, Series 5 is fully washable under running water¿or available with Braun¿s patented Clean & Renew system. An integral, adjustable long hair trimmer for beard, moustache and sideburns and a choice of elegant color combinations completes the package.
