Design: The wireless mouse is very small. It easily slips into a laptop bag, making it perfect for travel. The Nano receiver can be stored on the back of the mouse when not in use. Dual Modes: BT5.1 + 2.4G. You can use the mouse on two computers – one via Bluetooth connection and the other via the USB interface, simplifying your life. Silent Design: The two buttons are specially designed to be silent when clicked. This avoids disturbing others, allowing you to focus in libraries, offices, living rooms, cafes, and other public places. Working Distance: Features a 10-meter working distance and 3 adjustable DPI levels (800-1200-1600 DPI), allowing you to control mouse speed freely. Rechargeable Design: Our rechargeable mouse has a built-in rechargeable battery that can be charged via USB cable. Its superior automatic sleep technology helps ensure long battery life.
