Braun M-90 Beard Trimmer is a compact, fully washable grooming tool designed to shape mustaches and beards with precision. Its SmartFoil system uses a wide, ultra-flexible foil that adapts to facial contours for a close, comfortable shave. The twist cap provides a secure grip and protects the foil when not in use. A slide-out long-hair trimmer handles longer hairs for mustache and sideburn detailing. Powered by rechargeable batteries, the M-90 runs approximately 45 minutes per charge, with a 60-minute charging time. No plug is required during use, making it ideal for travel. The device is washable under running water for easy cleaning and maintenance.
