TECKNET Ergonomic Mouse, Wireless Bluetooth Vertical Mouse(BT 5.0+BT 3.0+2.4G), 6 Adjustable Levels up to 4800 DPI, Optically Quiet Wireless Mouse for Laptop/PC/Mac/Tablet/iPad(Win/Android/iOS), 6 Buttons

["Ergonomic Design"] This ergonomic wireless mouse ensures that the arm and wrist are held at a natural 52° angle, allowing the forearm and wrist to be in a more natural and relaxed position. This minimizes the risk of injuries from repetitive strain and reduces muscle tension in the arm. Ideal for web surfers, gamers, and anyone who spends a lot of time in front of the computer (Note: The mouse is designed for right-handers only). ["Seamless Switching Between Three Devices"] The ergonomic mouse features Bluetooth (5.0/3.0) and 2.4 GHz USB modes for connectivity. When connected via Bluetooth, the vertical mouse can effectively reduce the use of the USB-A port (Bluetooth mode can connect to two devices simultaneously), which is convenient for devices without USB ports. To switch to the 2.4 GHz mode, simply plug in the USB receiver to quickly establish a connection without the need for additional software installation. With just one press of a button, you can switch between the two modes and increase your work efficiency. ["Higher DPI & 6 Adjustable Levels"] This ergonomic vertical mouse is equipped with a high-performance chip and has 6 adjustable DPI levels (4800/3200/2400/1600/1200/800) to meet your daily requirements. The improved wireless mouse technology ensures smooth operation of this ergonomic mouse on different surfaces. When changing the DPI setting, the light blinks, with the number of flashes corresponding to the DPI setting. ["Silent Mouse"] This computer mouse operates silently, making it suitable for quiet environments like libraries. Additionally, the vertical mouse provides almost silent clicks, helping to prevent disturbance to others and allowing you to work or study without interruption (Note: Only the left and right mouse buttons are silent; other function keys are not silent). ["Wide Compatibility and Low Battery Warning"] The wireless computer mouse is compatible with various devices, including Windows, Mac, Chrome, and Linux laptops (side buttons not compatible with macOS). Furthermore, the Bluetooth laptop mouse switches to power-saving mode (complete power shutdown) after about 8 minutes of inactivity and can be reactivated by pressing the right or left button. Note: We recommend using brand batteries to ensure long mouse life. The LED light flashes when the battery is low (2 AAA batteries not included).
