Negative Positive
Title: Bad ergonomics
Review: Great Trackball, poor design. Using the Trackball makes you bend your wrist backward too much. The top of the ball is quite a ways above the table making it awkward to use. The Trackball system is excellent. The pad supplied does not raise the wrist anywhere near the right height to use this comfortably. You need almost a 2 inch thick pad. You could raise the area in front of the Trackball a couple of inches, but the unit is expensive and that shouldn't be needed.
