I originally received this mouse on time, but it broke after 3 days. Hoping it was an accident I contacted the seller and they sent me a new one. Received today, on account, we will see. I love the mouse and hope that it holds. When it REALLY worked, it was great! Cool looks and colors, correct rates of change. And NO, you don't have a choice of a specific color. Too bad. Also, colors (except for the brightest ones) don't come out as bright as in the center and back of the mouse, but it's still very cool. The only thing I wish is the brightness of the LED, which should be higher, and the brightness should be evenly distributed over the entire perimeter of the case.
