This mouse connects via a unique USB cable. This cable is red and also has a rubbery feel to it. Once you plug it in, you'll notice that the crosshair just above the "Cyber Snipa" logo lights up and the scroll wheel lights up. This scroll wheel lights up in three different colors. It's off when the DPI is 400, but when the DPI is 800, the red light is on. The green light comes on at 1200 DPI and the blue light is on at 1600 DPI.
