The R.A.T. 7 has a "precision aim" function which changes your DPI at the push of a button. This mouse can have DPI settings of anywhere from 25 to 6400 DPI.
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.
