This Philips Beard Trimmer Designed to prevent scratches and irritation, the blades have rounded tips for smoother skin contact. An effective beard trimmer that cuts to the exact length you’re after. Just spin the zoom wheel to one of 20 length settings between 0.5 and 10mm in 0.5mm increments. The battery indicators in this trimmer let you know what your battery status is: Low, empty, charging or full. This way, you can charge your trimmer on time and fully, so you won't end up with an empty battery in the middle of your trim.
