2.4G and Bluetooth 5.0 Dual Mode: This creatively designed and convenient mouse can operate on TWO DEVICES, connecting one device via Bluetooth and the other via RF 2.4Ghz. If you're tired of needing a separate Bluetooth mouse and a 2.4G wireless mouse for your laptop and tablet, or laptop and laptop, or laptop and desktop, this mouse is your ideal choice. You can intelligently switch modes between both devices with just one click. 7-Color Backlight: Features 7 different LED light colors that change during use, offering soft ambient lighting (Note: when colors change automatically and do not stay on a single color, the LED light cannot be programmed and changes regularly with 7 colors). Reassuring LED lighting provides the most transparent light effect, suitable for various gaming demands, making your mouse multi-colored and your imagination vibrant. Rechargeable and Ergonomic Design: Running out of battery power? Never again: Charge the mouse with the included micro USB charging cable as soon as the mouse is low on power. Fully charged, it operates for 6 months. The battery life is 500 times longer. Comfortable Design: Ergonomic design, perfect for all hands, fits comfortably in your hand, and the buttons are perfectly positioned for your office and gaming needs, preventing hand fatigue during prolonged use. The USB nano receiver can be stored at the back of the mouse.
