The Cherry Gentix 4k Corded Mouse is highly precise, even on 4K monitors. At 3600 dpi, the ultra-high-resolution optical sensor offers sufficient precision and speed to satisfy even the most demanding users of 4K monitors. The practical DPI switch allows users to conveniently change between the four pre-set resolutions via clicking. The red-lit scroll wheel is not just visually appealing but also provides information about the selected resolution. This wired mouse is streamlined at the back, making it ideal for both small and large hands.
