The Rowenta TN9140F4 is a versatile 13-in-1 multi-trimmer designed to handle everything from your beard and mustache to hair, nose, and ear grooming. Its stainless steel blades feature a titanium coating and a self-sharpening mechanism, ensuring a clean cut over time across a 44 mm width. You can easily customize your look using the slider control, which offers 26 different length settings ranging from 0.5mm to 18mm. This device is built for flexibility, operating either via a mains connection or its rechargeable Li-Ion battery, which provides 120 minutes of cordless use after a 1.3-hour charge. The Wet & Dry technology makes the housing waterproof and the nozzles washable, allowing you to rinse them under the tap for quick maintenance. A charging indicator light keeps you informed about the battery status while you work. The comprehensive set includes six combs, two shaving heads, and a dedicated nose trimmer head, all stored in a practical case alongside lubricating oil and a cleaning brush. This makes it a practical choice for anyone seeking a single, domestic tool to manage all their facial and head grooming needs in one place.
