ProtoArc EM05 NL Vertical Trackball Vertical and Bluetooth DPI 7 USB Compatible with and Ideal for Long PC Work at Home Mouse, 62° Orientation, 2.4G

🌈🌈🌈Vertical Trackball Mouse🌈🌈🌈 The 62° tilt of the trackball body reduces wrist strain by allowing you to maintain a natural wrist angle. This vertical thumb-type trackball allows you to operate the mouse without moving it, helping to reduce arm fatigue. This wireless trackball mouse allows you to operate it on a comfortable surface, such as your lap, or in your preferred position, significantly reducing wrist movement and significantly reducing elbow strain. The large 34mm ball provides excellent control and is ergonomically designed to fit the anatomical structure of your hand and arm. 🌈🌈🌈Connects to 3 Devices🌈🌈🌈This vertical trackball features one USB receiver and two Bluetooth devices, allowing you to connect to three devices simultaneously with multipoint functionality and quickly switch between them using the button on the back. When using multiple devices or monitors simultaneously, simply press the switch button to switch between them. The number on the switch button flashes, making it easy to check the connection status. This Bluetooth mouse offers stable connectivity and can be used with Windows, Android, and Mac OS PCs with just one mouse. 🌈🌈🌈Rechargeable and Eco-Friendly🌈🌈🌈This wireless trackball mouse is battery-free and eco-friendly thanks to its Type-C-USB rechargeable design. It features a durable 500mAh high-capacity battery, which can be fully charged in approximately 2-3.5 hours using the included charging cable, providing approximately 120 hours of continuous use and 200-250 days of standby time. Fewer recharges mean fewer batteries, eliminating the need for frequent battery changes, making it good for both your wallet and the environment. It also features an energy-saving mode that puts the mouse into sleep mode when not in use. 🌈🌈🌈5-Level DPI Adjustment🌈🌈🌈 The ProtoArc trackball mouse offers easy DPI adjustment from 200 to 400 to 800 to 1200 to 1600, high precision, and ease of use. It also offers numerous buttons for flexible operation. Compared to a standard mouse, the ball provides smoother operation, dramatically improving the efficiency of your computer work, especially with dual monitors. [Please note that this trackball mouse is not suitable for extremely delicate operations such as gaming or drawing.] 🌈🌈🌈Space-Saving🌈🌈🌈 Not only does it provide smooth ball movement, but it also takes up significantly less space on your desk, eliminating the need to move the trackball mouse around. Its wireless design also offers excellent portability. Unlike wired mice, you can use your computer from your desk, sofa, or even in the comfort of a futon or kotatsu (Japanese-style table) when it's cold, without needing a mouse pad. [Size Notes] As a vertical trackball mouse, the EM05 Trackball Mouse is best suited for medium and small hands. Please note that larger hands may find the space for their pinky finger to be limited and difficult to get used to.
