The Genius Ergo 8350S in Dark Gray is a wireless vertical mouse designed to reduce wrist strain through a natural 55° palm inclination and a dedicated thumb rest. It offers flexible wireless connectivity via Bluetooth 5.3 or a 2.4GHz USB receiver, allowing you to switch between devices, though only one mode can be active at a time. To help you work more efficiently, it includes a specialized button that instantly activates AI Copilot, alongside six functional buttons including forward and backward controls. Its optical sensor provides three adjustable resolution settings, reaching a maximum of 2400 DPI (1200, 1600, and 2400), so you can tune the cursor speed to your preference. The device is built for a quiet environment with silent-click switches and weighs approximately 81g, making it easy to move across your desk. Measuring 67.3 x 105 x 58.4 mm, it fits comfortably in the hand and operates at a distance of up to 10 meters. A built-in power-saving switch helps extend the life of the included AA battery, ensuring the mouse remains ready for use across Windows, macOS, ChromeOS, iPadOS, and Android systems.
