Title: Uncomfortable to use
Review: The layout of the trackball is just wrong. The designer expected the user to use the middle and the ring fingers to move the ball. The problem with that is my middle and ring fingers are not train to provide fine movement as my index finger can. I tried to shift using the index finger from the ball to the wheel. Then the problem is the distance between the wheel and the ball is too far apart. And by shifting the fingers back and forth, I suffers lag time. In addition, I have to stop using it in about 15 min because my fingers and wrist are killing me.The trackball is just unconfortable to use and not that egonomic which trackball supposed to be. Skill it.
