The UGREEN MU001 Wireless Mouse in Grey is a compact productivity mouse designed for quiet daily use across laptops and desktops with a standard USB-A port. Its neutral grey finish works well in office environments while the slim body keeps the mouse easy to carry in a notebook bag. Wireless communication uses a dedicated 2.4GHz nano receiver rather than Bluetooth. That means setup is simple: install the battery, insert the receiver and use the mouse without device pairing menus or extra software. The stated wireless range is up to 10 metres under suitable conditions. The optical sensor provides four hardware sensitivity settings at 1000, 1600, 2000 and 4000 DPI. A user working on a large display can increase pointer speed, while more controlled tasks can use the lower settings. No specialist driver is required for these basic DPI changes. UGREEN uses a symmetrical design suited to left- or right-handed users. Reduced-noise clicks help keep the workspace quieter, and automatic sleep behaviour is designed to extend the life of the single AA battery. Battery life is quoted up to 18 months under the manufacturer's test conditions. The grey MU001 is a strong fit for office, study and travel use where quiet input, adjustable sensitivity and low maintenance matter more than gaming macros or Bluetooth multi-device switching.
