That means no nasty nicks, and no bristly leftovers. Braun's smooth glide is helped by floating blades and a shaver head that tilts 40°. It pivots with the contours of your face - even in tricky spots like the jawline. And when you need extra control, just hit the Precision Switch. It locks the head to make sure you can get every last follicle.Good to know- Feel free to use the 100% waterproof shaver with foam, gel or even in the shower- Thick, tangly, flat? Even the most uncooperative hair isn't a problem because the ProLift trimmer lifts as it cuts- AutoSense tech adapts every stroke to the thickness of your beard - it's more efficient, gentler and able to tackle dense beards- For precise detailing and defining sharp edges or neck lines use the pop-up precision trimmer- Don't get caught out by low battery life
