The Genius Ergo 8100S is a wireless ergonomic mouse designed to reduce hand strain during long hours of computer use. It connects via a 2.4 GHz RF wireless link using a small USB receiver, allowing you to move freely without cables. To suit different tasks, you can toggle between 800, 1200, and 1600 DPI using the dedicated switch, which adjusts the cursor speed for either precision or rapid movement. This mouse features a silent clicking mechanism that minimizes noise, making it a considerate choice for shared offices or quiet home environments. Its sculpted body measures 67.8 x 109.5 x 38.4 mm and weighs approximately 60 g, providing a lightweight feel that complements its ergonomic shape. Along with the standard left, right, and scroll buttons, it includes forward and backward buttons to simplify web browsing. Powered by a single AA alkaline battery, the device is compatible with Windows 8 or later and macOS X 10.8 or later. It is available in black, iron grey, and champagne titanium finishes, offering a professional look for anyone seeking a more comfortable and quieter way to navigate their desktop.
