The Gembird MUSW-4B-04 in black is a wireless optical mouse designed with an ambidextrous shape, making it comfortable for both right- and left-handed users. You can easily adjust the tracking precision to suit your current task by switching between 800, 1200, and a maximum of 1600 DPI using the dedicated button, while the four-button layout provides a straightforward interface for daily navigation. Connectivity is handled by a compact Nano USB 1.1 receiver that plugs into your computer's USB interface, staying out of the way thanks to its tiny 6 x 14 x 18 mm dimensions. The device runs on two AAA batteries, allowing you to work freely without the restriction of cables in environments ranging from -5 to 45 degrees Celsius.
