It's easy to use, you only have to click start button and do the movements you want to track. Then, stop and play those movements whenever you want.
That's very useful if you want to do clicks, open windows and other things automatically when you are away.
It's very useful to earn points in games like Farmville automatically at night.
Finally, not only does it track mouse movements but it can save keystrokes too.
