Could be a dead thread but it was high on the Google ranking. Anyways, I have had the Ouroboros for about a week now and it looks nice but currently the driver support on OSX 10.8 is awful. Called support and they were friendly but offered no solutions other than 'wait until we support Mountain Lion', pretty bad for a $150 mouse. Mouse without drivers means you get 3 buttons and a scroll wheel, mouse with drivers doesn't work (pointer skips around, button settings get erased sporadically, calibration changes sensitivity without cause).

I'm sure it'll get better but for now this mouse is $150 for a 3 button generic mouse.
