I had a Microsoft trackball for a while. It was a big thing, very clumsy.
The ball would stick a lot, and felt rough when I rolled it.
I replaced the Microsoft with a Logitec wireless. For the first month or so it performed flawlessly, and I loved it. But recently, the ball has begun to stick occasionally, and feels rough at times. I can fix the problem by rolling it vigorously this way and that. But it seems that eventually when I want to make slight movements the ball will stick.
All I can say is that these things are not designed for precise movement.
I will probably return to the mouse, which I am trying to avoid due to stress I get in my shoulder when using it.
