When deciding on the best gaming mouse, Razer and Corsair are two brands that come to mind first. Each manufacturer took different routes to becoming the premier maker of gaming mice, keyboards, and headsets. From its inception, Razer has targeted the gaming world with stylish, high-performance peripherals. On the other hand, Corsair first made its name with other PC components like cache modules and memory sticks. Corsair still has a broader inventory of products than Razer, but that hasn't prevented them from introducing innovative gaming mouse technology.
