Logitech® Wireless Mouse M280 is the perfect synthesis of functionality, aesthetics and comfort: a unique asymmetric shape that fi ts well, a wide wheel that improves scrolling and a soft rubber surface with distinctive patterns that improves touch feeling. Tracking is smooth and precise with Logitech Advanced Optical Tracking. Our energy-effi cient engineering gives you an 18-month battery life* and the mouse automatically puts itself to sleep when you’re not using it. Finally, the tiny wireless receiver practically disappears in your computer’s USB port and provides a convenient and reliable wireless connection. * Battery life may vary based on user and computing conditions
