Philips Prestige 9000 Series Beard Trimmer Black/Silver delivers unmatched precision thanks to the built-in metal comb, giving consistent trimming results no matter how much pressure applied. It always follows the contours of your face, with an anti-friction coating that allows it to effortlessly and comfortably glide over the skin. Full metal blades remain sharp for life. And due to the special geometry of the blades, they cuts even the thickest hair without pulling. The steel beard trimmer reads hair density 125 times per second. The Power Adapt Sensor automatically adapts the motor to maintain constant power and deliver effortless trimming performance. It gives up to 120 minutes of cordless trimming time from a full 1-hour charge, or charge for 5 minutes for a quick trim. Its high quality stainless steel body is hand-finished with ultimate attention to detail-giving you a lasting premium experience. It has 3-level battery indicator that shows when the battery is full, running low, or if it's charging. It is 100% waterproof so simply rinse it under the tap for a thorough, easy clean. It also has premium travel case that keeps everything together when you’re at home or on-the-go.
