The CHERRY GENTIX 4K is based on the international best-selling GENTIX mouse, with many unique functions added to it. 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 preset resolutions via clicking. The red-lit scroll wheel is not just visually appealing but also provides information about the selected resolution. The mouse wheel can be lit permanently or only flash briefly when you change the resolution - the choice is yours! Two additional thumb buttons allow you to rapidly navigate back and forth in your browser. The rubber-coated side parts are unchanged. They provide a firm grip and feel pleasant in your hand. The design is streamlined at the back, creating perfect ergonomics to make the mouse ideal for both small and large hands. The 1.8m cable provides flexibility, allowing you to connect the mouse to the PC below your desk, if necessary.
