Mouse UGREEN 90855 Wireless Optical USB 2.4GHz Bluetooth 5.0 4000 DPI Black

UGREEN MU006 is a full-size ergonomic wireless mouse that connects via Bluetooth 5.0 or a 2.4 GHz USB receiver. It supports pairing with two devices simultaneously and offers an adjustable optical resolution from 800 to 4000 DPI. The device has six quiet buttons, works on many surfaces without a special pad, and is powered by a single AA battery (not included) with an automatic sleep mode to conserve energy.

Advantages

The MU006 provides dual wireless connectivity (Bluetooth 5.0 and 2.4 GHz) and a connection range up to 15 m. Adjustable DPI levels (800 / 1000 / 1600 / 2000 / 4000) allow precise tracking for office tasks, photo editing or casual gaming. Its ergonomic shape and six silent buttons reduce hand fatigue and allow quiet operation in shared or quiet environments. The mouse delivers long battery life — up to 18 months under typical use — and durable buttons rated up to 3 million clicks.

Suitable for

• Home and office work — document editing, browsing
• Photo editing and graphic tasks requiring adjustable sensitivity
• Casual gaming where up to 4000 DPI is sufficient

How to use

Install a single AA battery into the compartment, insert the 2.4 GHz USB receiver into your computer or enable Bluetooth on the target device and pair with Bluetooth 5.0. Use the DPI button to switch between sensitivity levels (800–4000 DPI). The mouse will automatically enter sleep mode after a period of inactivity to save power; press any button or move the mouse to wake it. For dual-device use, follow the pairing procedure for each connection method and switch between devices as needed.

Recommendations

To maximize battery life, enable sleep mode when not using the mouse, turn off Bluetooth on idle devices if possible, and store the USB receiver in the mouse’s compartment (if applicable) when transporting. For best tracking, use the mouse on flat surfaces such as wood or fabric; no special pad is required.
