Prepare to be blown away by the centrepiece of the EXATI mouse: auto dpi adjustment. It's an incredible bonus whether for gaming or working as the mouse-pointer speed adjusts automatically to your actual movements and the way you are using the mouse. When you need pixel-perfect precision, such as for image editing, the sensor resolution decreases - resulting in a slower, easier-to-position mouse pointer. If you want to move quickly from one corner of the screen to the other, the resolution increases dynamically - accelerating the mouse-pointer speed with zero loss of precision. And with its ergonomic comfort and quality build, the EXATI is a premium tool for everyday use.
