When it's do or die, timing and precision are everything. The Cyborg R.A.T. 9 Gaming Mouse delivers zero latency, a precision aim mode, and twin eyer laser sensors allowing you to hit your target every time with the same lightening fast speed and accuracy you produce. With two custom lithium-ion battery cells, you'll always have one charged and ready to go for up to 4 days of normal use. Although, we do recommend pausing for things like showers.
