The Philips BT3620/15 is a versatile beard trimmer from the 3000 Series designed for precise grooming of the beard and mustache. It features a precision dial that allows you to choose from 40 length settings in 0.5 mm increments, ranging from a short 0.5 mm stubble to a fuller 20 mm look. To ensure a comfortable experience, the non-corrosive, self-sharpening blades are designed with rounded tips to prevent skin irritation during use. This black trimmer is built for convenience with a 100% waterproof body, meaning you can use it comfortably both wet and dry. It is powered by a Li-Ion battery that provides up to 70 minutes of cordless runtime after a 4-hour charge via the included USB cable. A built-in battery indicator light helps you keep track of the remaining power so you are not caught off guard. The package includes the trimmer unit and two lift-and-trim combs covering the full range of lengths, along with a cleaning brush for easy maintenance. This setup is well-suited for anyone looking for a reliable domestic tool that offers a wide variety of styling options in a durable, water-resistant design.
