Corsair Ironclaw RGB @ TechPowerUp
 

Even though its name might suggest otherwise, the Ironclaw is a huge palm-grip-oriented mouse, and it's the newest creation of Corsair. It comes with an all-new top-notch optical sensor called the PixArt PMW3391. The mouse also features Omron D2FC-F-K switches with a nominal lifetime of 50 million clicks, two zone RGB lighting, and a robust, highly durable shell.
