3D Rotation & Auto Sharpening: Our electric shaver features a 3D swivel head design with 2 independent blades that freely rotate to conform to the contours of your face, neck, and chin. With automatic sharpening, there's no need for frequent blade replacements. Simply rub the inner and outer blade to maintain sharpness. For stubborn whiskers, a combination of foam and gel works best. Plus, the automatic polishing system keeps the blade sharp at all times. (Note: Not suitable for dark whiskers.) IPX6 Waterproof and Removable Design: This wet and dry electric shaver is shower-friendly, thanks to its IPX6 waterproof rating. The magnetic shaving head is removable for easy cleaning. Equipped with a beard density sensor system, it automatically adjusts the power for optimal performance. Its flexible head adheres to the unevenness of your face, reducing irritation during shaving. Super Strong Motor / 50 dB Low Noise: The dual steel precision blades cut up to 90,000 times per minute for a thorough shave. The high-speed motor ensures quick and sharp shaving while being gentle on the skin. With one-button operation, you can achieve a powerful shave without worrying about pulling the beard. The shaver operates at a low noise level of 50 dB, allowing you to use it comfortably even during early mornings or late nights. USB Type-C Charging: Our men's electric shaver supports USB Type-C charging, providing convenience and versatility. With normal use, it can last up to 30 days.
