Q: I found the trackball too sensitive despite numerous attempts to change the settings. I ended up spending too much time trying to line up the pointer and click ... this was especially true on smaller buttons. I suspect that a thumb just isn't the best choice for fine motor control once you've reached a certain age, and the small ball made this even more obvious. In fairness, I am \"north of 50\" and someone younger might have a different experience ... as the other reviews bear out. So for me, the ball was jumpy and erratic ... not a good choice. Better software ... something with greater control of acceleration could certainly help, but I wan't able to do much with Logitech's included application. I've returned the unit and am looking for a second choice.
A:
Trackball control simply not smooth
