The Genius NX-8025S in black is a wireless silent mouse designed to provide a quiet and efficient workspace. It uses 2.4GHz wireless technology to maintain a stable connection with your computer at a distance of up to 10 meters, utilizing a small USB RF receiver. The optical sensor offers a default resolution of 1200 DPI, though you can adjust this up to a maximum of 1600 DPI (between 800, 1200, and 1600) to match your preferred cursor speed. Beyond the standard left, right, and scroll buttons, this mouse features a dedicated key to quickly activate the Windows Copilot AI assistant on Windows 11 or newer systems. Its ergonomic contoured shape is designed to fit comfortably in either hand, while the silent click mechanism ensures that your work doesn't disturb those around you. Weighing only 58g and measuring 65 x 108 x 37.8 mm, it is light enough for easy transport in a laptop bag. Compatible with Windows 8 or later and macOS X 10.8 or later, the device comes ready for use with an included AA alkaline battery.
