With included Mad Catz Cyborg Engine software, you can easily customize this mouse to fit your needs, including setting hot keys and macros, creating up to four loadout profiles stored on the mouse, and more. The unique barrel side scroll wheel can be easily customized to quickly select weapons even under tough gaming conditions. The precision button instantly increases or decreases the sensitivity, perfect for in-game sniping. An adjustable DPI button lets you increase or decrease the DPI instantaneously, up to 16000. Create the perfect grip with the adjustable palm rests or swap them out entirely to fit any hand size. The pinkie rest comes with three variations (battle-ready, wing and rubber) for even more customization and control. Precision engineered for quality and durability, this mouse is constructed with a 100g solid aluminum alloy chassis. The patented DAKOTA Switch gives you near-instantaneous response times that are 60% faster than traditional mechanical switches. This advanced switch also gives the R.A.T. DWS an industry-leading 60-million click lifetime.
