When I first saw this mouse I wasn’t too impressed, compared to other gaming mice it was lacking the initial wow factor that draws you to it. The M3x offers an on the fly DPI adjustment, however you must pick between eight predetermined settings (no customizing here). The eight options are associated with a colored LED so you would have to memorize which color coincides with each resolution. The DPI selection is on a cyclic system, in other words you have to cycle all the way through to get to a lower DPI. I found this irritating, and almost counter-productive.
