I don't believe Razer makes the best mini gaming mouse, the Deathadder v2 Mini is sweet and all, but the Cooler Master MM710/711 (the revised model, latest) has a more responsive click and it better obeys the hand. Nonetheless, I am going to start and game with the Mini and see how it goes.
I have an original M710, and though it was awesome the build quality sucked, the button was way too loose, but Cooler Master remedies that and hence I had my mouse replaced, and now it is absolute solid.
I also didn't get the Mini to replace my M710, but to replace my G403. The Mini turned out to be quite smaller than the M710, but it is still at home with my grip.
All I want solved now is this stupid loss I am experiencing. I can't game CS this way any more.
