As the world's first laser-guided beard trimmer, the Philips' BT9297/13 delivers perfect symmetry and a professional finish every time. Simply follow the red line of light to get a sharp, even trim on both sides of your face, and leave the double-sharpened metal blades to effortlessly cut through even the thickets hair. As you trim, these strong and durable blades sharpen themselves by lightly brushing against each other, for long-lasting performance. Philips' innovative lift-and-trim system even raises each hair before guiding it towards the blades, producing perfectly even stubble in one go. Trim in precise steps of 0.2mm, ranging from 0.4mm to 7mm, and style your beard with ultimate accuracy. You can use the zoom wheel to select and lock in the length you want, while the LED display clearly shows your chosen length setting as well as the status of your trimmer's battery. Thanks to the skin-friendly rounded tip, the BT9297/13 prevents irritation as you trim, even without a comb. What's more, the detail trimmer quickly clicks in place and creates immaculate, defined edges for your beard or moustache. The Series 9000 Beard Trimmer is even 100% waterproof for easy, thorough cleaning under the tap.
