Yeah, I just opened my Mamba 2012 and connected it to my PC, yay! But it has a problem with DPI setting. It sets its DPI to lowest value so the mouse gets really slow. Synapse makes the fatal error. And the Wired/Wireless mods are not working fine. Of course, whole mouse and drivers are in poor status. I searched about this topic on Google, other people have same issue with me. How's your guys? Are you fine with your Mamba or not? Razer must fix this problem.
