UGREEN MU008 (25444) Wireless (Dual Mode) Black Silent Vertical Mouse

The UGREEN MU008 (25444) Wireless (Dual Mode) Black Silent Vertical Mouse is an ergonomic and highly versatile wireless mouse designed to reduce wrist strain while offering responsive performance for everyday computing tasks. It features a vertical ergonomic design with a 57° angle that aligns your hand in a more natural handshake posture to help reduce fatigue during long use sessions. With dual‑mode wireless connectivity, you can connect via Bluetooth (5.0) or a 2.4 GHz USB dongle, and you can even pair up to three devices simultaneously — two via Bluetooth and one via the USB receiver — and switch between them easily. The optical sensor supports adjustable DPI levels from 1000 up to 4000, allowing fine control for precise tasks or faster cursor movement for general use. Its silent buttons and scroll help keep noise low in quiet environments like offices or libraries, and the built‑in auto‑sleep power‑saving mode helps extend battery life (up to many months on a single AA battery, not included). With stable wireless performance up to about 10 m and broad compatibility with Windows, macOS, Linux, Chrome OS, and Android devices, the MU008 is a comfortable, adaptable choice for anyone seeking ergonomic comfort without sacrificing connectivity or performance.
