“No need to buy a gaming mouse made for everyone, build the gaming mouse made just for you,” with this tag line comes new Mad Catz R.A.T. Pro X3 Supreme, a modular mouse that comes with a whopping 108 different physical configurations. This is a limited edition mouse (in celebration of the Chinese Year of the Rat) which offers up three different palm rests, two choices of size and material for the pinkie rest, two sets of thumb rests, a pair of customizable scroll wheels, and the choice between ceramic or Teflon feet for different levels of gliding resistance. This is powered by a PixArt PWM3389 optical sensor offering up to a 16,000 DPI and 400 inches per second of tracking, along with a 3,000Hz (0.3ms) maximum report rate. It also has 10 programmable buttons, with the primary switches being the Omron switches good for 50 million clicks. And of course, RGB lighting is also customizable. The one thing it lacks is the accommodate left-handed usage.
