The Genius ECO-8100 is a wireless rechargeable mouse designed for versatile daily use. It features BlueEye technology, which allows the sensor to track accurately on a wide variety of surfaces, including glass, marble, carpet, leather, and denim. You can adjust the resolution between 800 and 1600 DPI to suit your precision needs, while the three-button layout with a scroll wheel provides standard navigation for Windows and macOS systems. Constructed from ABS plastic in a green finish, this ambidextrous device weighs 81 g and measures 106 x 59.5 x 37.1 mm, making it comfortable for both left- and right-handed users. It connects via a 2.4 GHz RF wireless link using a USB-A receiver. Instead of disposable batteries, it uses a built-in rechargeable NiMH battery that charges via the included USB-C cable, requiring an initial 10-hour charge before its first use.
