Cons
Con Laser (not optical) sensor
Laser sensors are just not that great when compared to optical sensors. Often there is acceleration issues with laser sensors.
Con Expensive for what the internal hardware is
Sadly the components inside of this mouse are pretty cheap, ranging from the switches to the laser sensor. For the price Mad Catz is charging one should expect higher quality components.
Con Forward / back buttons wear easily
The two buttons located on the side of the mouse (sometimes known as the page forward and page back buttons for internet browsers) wear out easily after only a few months of usage. That means that it requires extra force to register a button press, all while receiving no touch (or audible clicking) feedback. Frustrating but the mouse does continue working.

Con Uncomfortable "seam" where your thumb and palm meet
Con Side buttons can irritate ring finger
The ambidextrous extra buttons on the side may rub against the ring or pinkie fingers.
