Some pros: This is by far the best ergonomic mouse I've ever owned. The brush does not hurt and does not ache from the fact that you have to work for hours at the computer. With its cons: Backlight, it can not be turned off or switched to another color. Periodically, the mouse is taken to the corner of the screen from any speck of dust on the surface.
I thought some photos would help to make my review more informative.
