The Genius Ergo 9000S in black is a wireless mini ergonomic mouse designed to provide a comfortable grip in a compact form. It offers dual-mode connectivity, allowing you to switch between Bluetooth 5.0/5.3 and a 2.4GHz wireless connection via a USB-A receiver, which means you can stay connected to up to three different devices. This versatility makes it a practical choice for those who move between a laptop, tablet, and smartphone throughout the day. Equipped with an optical sensor, the mouse features adjustable resolution settings of 800, 1200, 1600, and a maximum of 2400 DPI to suit your precision needs. It includes six buttons, including dedicated forward and backward keys and a DPI switch, all of which operate with silent clicks to avoid disturbing others in quiet environments. Weighing only 53g and measuring 68.2 x 90.7 x 39.3 mm, its lightweight build and ergonomic shape reduce hand strain during extended use. Power is supplied by a single AAA battery, and a built-in power-saving switch helps extend the battery life. The device works across a wide range of systems, including Windows, macOS, ChromeOS, iOS, iPadOS, and Android, ensuring compatibility regardless of your operating system.
