Focus + Optical Sensor. Our new improved sensor has an industry-leading 20,000 DPI with 99.6% resolution accuracy, ensuring that even the best movement of this wireless mouse is tracked evenly. Equipped with smart features, the sensor becomes even more accurate, allowing a high level of precision for the game-winning head shot. Asymmetric cut. In addition to the elevation distance of the sensor, you can add another level of precision by using an asymmetric cut to set its landing distance, the distance at which the mouse tracks again. Ideally, you want it to be as low as possible so there is less cursor drift when the mouse touches the surface. Optical mouse switch Using an infrared beam of light to record every click, the switches on this wireless mouse operate with an industry leading response time of 0.2 milliseconds. Because it no longer requires traditional physical contact, this form of action eliminates the need for discharge delay and never triggers unwanted clicks, giving you closer control. 74g lightweight design.
