The scroll wheel is the sole feature of the M31R mouse that showcases RGB lighting effects. These can be customized via the official software provided by the manufacturer. There’s a built-in shortcut on the mouse itself (a long press of the side button, scroll wheel, and right button) that allows users to quickly turn off the RGB lighting. This is a handy feature for extending the mouse’s battery life during wireless operation.

It is worth mentioning that compared with the original Y-shaped pattern of the same series, the military green M31R roller pattern has been changed to a snake pattern to prevent slipping, and the sense of passage when rolling and pressing is equally clear and distinct.
