The Wireless Mouse M320 combines functionality, aesthetics and comfort. With its asymmetrical shape and the textured, soft rubber surface, it fits comfortably in the hand for long-lasting use. The cursor can be controlled with precision on a wide variety of surfaces, and the wide wheel facilitates smooth scrolling. The small USB receiver provides a reliable wireless 2.4 GHz connection. As the mouse is energy-efficient, a single battery will last for two years.
