Warm Tips: If you are using a trackball mouse for the first time, it may take some time to get used to its operation. We recommend that you spend 1-2 weeks to adapt, as many users find that this helps reduce the pressure and pain on the wrist caused by long-term use of the mouse and improves comfort ^^ You can download the driver by following the steps in the instruction manual to customize the mouse settings and fine-tune them to better suit your personal mouse preferences.
(Note: This driver is not compatible with Mac OS)
