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
