Review: This is a terrible mistake, all the functions are designated to the wrong fingers, and they are not naturally gifted with that dexterity. Nor are they likely to be able to adapt. Your middle finger or first finger are adapted to going up and down moving a wheel is logical, but not side to side on a ball. Your thumb, for most human like animals has the most motion dexterity and it is not even used here. I disagree totally with another TrackBall comment; the middle finger is far far over worked here and is not capable. Study the motion and evolution of the hand, the thumb is the progress of apes, the other fingers grab and make a fist the thumb works. I Have all of 5 or six warn out TrakBalls in my drawer, this is a problem with them, they ware out and bind. I tried this one for about two weeks exclusively every day, but could not get any speed out of it. I love track balls and can work easily faster with them.
