Adjust the DPI conveniently. You determine the pointer speed.
The adjustable pointer speed button of the Evoluent D is easy to reach. It is placed behind the wheel which enables quick changing of the pointer speed to suit different tasks: select higher speed (higher DPI) to make the pointer move faster for general use; select lower speed (lower DPI) to make the pointer move slower and more precisely for drawing, photo editing, etc. The favourable thing is, that four lights show the different pointer speeds from slow to fast.
