Razer Mamba 16000 DPI issues with wireless & software

So I've had the Razer Mamba (RC30-013601) for about 6 months now. I'm still annoyed by the fact that for some reason, this €150 mouse is not supported by Synapse 3. I have to use an older version of Synapse just for this mouse, while the rest of my set-up uses Synapse 3 flawlessly. Then, I've only used the mouse wireless for a couple of times because of connectivity problems. It just keeps losing connecting (stops moving in-game) for 0.1-0.5 seconds while playing FPS games. Of course, this is the difference between a kill or a death. I even went as far as to move the receiver right up to my mousepad, to no avail. Are these common issues? Will this mouse ever be supported for Synapse 3?
