The Cougar 550M Gaming Mouse stands out not only for its elegant dark gray metallic design with well-matching orange accents but also for its advanced technology. It features a proven optical 6,400 DPI sensor from Avago, combined with extremely durable and reliable microswitches from Omron. Together with the high-quality housing and rubberized side grips, Cougar has created a serious tool for winners.

The 550M has a total of six programmable buttons, including its scroll wheel, two main buttons, two thumb buttons, and an additional button behind the scroll wheel. Cougar's UIX software and three profiles stored within the mouse allow for extensive customization to meet individual preferences regarding button assignments and lighting. In addition to the DPI/profile indicator, the rear part of the mouse is also illuminated and can be set to a different color from the indicator using the UIX software—both areas feature RGB LEDs. The durable gaming buttons from Omron allow for at least 5 million clicks, and the mouse connects to the PC via a 1.8-meter long, braided USB cable.
