I took a trackball for a test, because from ordinary mice my arm began to hurt until it was impossible to work. Helped partially. Now at work, a regular mouse and this trackball are used alternately. The ball gradually gets dirty and starts to stick. But here everything is thought out: the ball needs to be rolled with effort - it will self-clean and slide again like new, and the debris will fall out of the hole from below. Some people deny this feature, but personally for me it works that way. Add: after a while, a better version of the mouse was found - a vertical mouse. And this trackball was left to work on the bed in a blanket, or where there is no surface for a regular mouse. In general, it is in reserve.
