This is an often overlooked trackball which is essentially the same performance as the highly rated Kensington Orbit With Scroll Ring.
They both use the same optical tracking technology and same size ball. I am willing to bet they use the same mouse clicking hardware. The only real difference is one has a scroll ring and one does not.
The scroll ring is not really needed and only scrolls up and down. Scince neither have a middle mouse button you need some sort of program to compensate and which can give you a better mouse scrolling experience than the scroll wheel.
I use "X-Mouse Button Control". It is free and open source. I use it so all I have to do is hold both buttons down and use the trackball to scroll not only up and down but side to side.
