Ranked in these QuestionsQuestion Ranking
Pros
Pro Reliable; keeps on going through the years
It will still work just as well as the day you bought it.
Pro Incredible flexibility
Many parts of the mouse are adjustable with interchangeable pinkie grips and palm rests to a custom weight system. The mouse is able to literally change its size and weight.
Pro Cordless version available
It also comes in a cordless version, called the RAT 9.
Pro Textured thumb rest
There is a textured thumb rest on the left side giving the user an area for their thumb to rest while also providing more grip for moving the mouse.
Pro Sniper button
The included sniper button will instantly decrease the mouses sensitivity while pressed in, giving the player an advantage accurately placing the cursor where it needs to be such as in headshots in an FPS.
Pro Aluminum housing
The M60 features a solid aluminum body at its core for a superior build quality.
Pro 8 programmable buttons
There are 8 fully programmable buttons on the mouse. This includes a 'sniper button' next to the thumb, which by default toggles a shifted DPI to allow for more accurate sniping while gaming.
Pro Adjustable weight and center of gravity
There are 3 removable weights in a triangle formation, allowing you to change not only the weight, but also the center of gravity.
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 Braided cable
The braided cable is stiff and may catch on the mouse pad on a regular basis.
Con Too light
The 3 weights and aluminum frame are just not heavy enough. If they were to add a weighted sled for more weight instead of 3 plugs, they could make it comfortable for a wider range of people. Satisfying both users who like light or heavy mice.
Con Finnish rubs off
The rubberized texture comes off the thumb rest and ring finger side around 2 months in. The slick plastic underneath is not a sure grip when moving around in game. Considering this is a gaming class mouse you would think they would use a textured finished material not a coating.
Con Laser sensor
The included Avago ADNS-9500 laser sensor is going to have trouble with acceleration.
Con Poor middle mouse button fail
Middle mouse button click stopped working reliably after about 2 months of negligible gaming.
