Hama WM-400 Wireless Ergonomic Mouse, Green

The Hama WM-400 Wireless Optical Ergonomic Mouse (HA-00173038, green) is designed for right-handed use in office or home settings. It uses an optical sensor with a maximum resolution of 1600 DPI for reliable tracking on standard surfaces. Users can switch between three sensitivity settings—800, 1200, and 1600 DPI—to adjust the cursor speed for different tasks. The mouse connects via 2.4 GHz wireless technology with a range of up to 10 metres. A compact USB-A receiver handles the connection and can be stored inside the mouse body. Six buttons provide standard navigation and control for daily use.

The mouse features quiet primary buttons to reduce noise in shared workspaces. Its ergonomic shape for right-handed users includes rubberised side grips for a secure hold, and PTFE feet on the underside to ensure smooth movement across mouse pads. The mouse is powered by a single AAA battery, which is included. It is compatible with Windows 7, 8, 10, and 11. Weighing 79 grams, it is light enough for mobile use. A scroll wheel positioned between the primary buttons handles vertical navigation.
