In the center of the rear we have the Tt eSports ‘Dragon’ logo, which is LED backlit. Both the left and right undersides feature a thin long LED strip. So that’s a bunch of LED lighting in the Theron: the mousewheel, the Dragon logo, the left/right underside and the DPI indicator. All these lights are programmable to show from a selection of 7 colors. Sitting on the Steelseries 4HD surface, the Theron looks absolutely sexy. The 4HD mousepad mildly reflects the Theron’s LEDs, and that makes the mouse look like a sports car with neon lighting, straight out of a Need For Speed game. The colour of the lights can be switched from a button at the bottom of the mouse, or the software. The LED lights can also be programmed to give a pause-break effect, depending to how fast you’re clicking the buttons.
