Pros
Pro Reliable; keeps on going through the years
It will still work just as well as the day you bought it.

It also comes in a cordless version, called the RAT 9.
Pro Tons of easy to program buttons
Great for MOBAs, MMOs, and even FPSs.
Pro Side buttons are mechanical and angled

The scroll wheel can be pressed left, right, or down.
Pro Braided cord
Pro Super comfortable to use
Perfectly conforms to any grip type in your hand. Can use this mouse for hours on end.

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 The shape will not feel comfortable for everyone
The shape does not work with palm grips that well.
Con Heavy
Unsuitable for most hardcore FPS games. This mouse will easily make your hand tired due to its weight of 135g.
Con Side buttons are not for everyone
Takes your thumb some getting used to, hitting the correct button.
Con Proprietary software needed to take advantage of all of the mouses features
Users will need to install Razers Synapse software to take advantage of most of this mouses features such as the programmable keys.
