It has 3 "on-the-fly" dpi buttons which you can set to what dpi you want. The dpi settings goes up in 250 intervals, 750-1000-1250 etc. The lowest dpi setting is 250 while the highest is 4000dpi.
It is a wireless mouse but when the batteries get low, there is a cable wich has a magnetic end and simply attatches to the bottom of the mouse so you can still play and charge.
There is 8 buttons alltogether (left & right click, 2 buttons on side and a mouse 3 and mouse tilt left & right and a macro button). Every buttons function can be changed and even for different programs. The mouse comes with a little round container which holds little mouse feet for different frictions, 3 sets of mouse feet in total.
