How to use

Plug the mouse into an available USB-A port on your computer; the device typically registers automatically without additional drivers. Place your hand on the housing so your thumb or fingers rest comfortably on the trackball, and move the ball to control the on-screen cursor. Use the left and right buttons for standard click operations. For optimal precision, keep the trackball and surrounding area clean and free of debris.

Recommendations

Regularly clean the trackball and its housing to maintain smooth operation. If extended comfort is a priority, adjust your desk and chair height so the forearm rests naturally while using the mouse. For tasks requiring extreme pointing accuracy, combine the trackball with appropriate pointer settings in the operating system.
