3D Anti-slip Roller: To improve grip, the Meetion gaming mouse has a 3D anti-slip roller. During extended use, this anti-slip feature provides your wrist with the comfort and support it needs. Use our PC mouse to enhance the enjoyment of your gaming sessions! Unique Design: The comfortable claw-grip design of our computer mouse allows for prolonged use without fatigue. Normally, a mouse can cause cramps after extended use, but ours doesn't. Even after using your hand for hours on end, it will feel relaxed. Four-Speed DPI: The DPI on this wired gaming mouse has four speeds. You can change the mouse's sensitivity to a faster or slower pointer speed thanks to this feature. Your entire computer and gaming experience is improved by doing this. Another key feature is the side button.
