So yes, the buttons on the side change lives throughout mmo, for the rest, up to you, it can serve in office.
But I am disappointed with several problems:
-If You use the software Razer Synapse 2.0 to configure a mouse pad with this mouse, well, every Windows boot blocked your mouse ... This is not serious, but still.
-The Laser is on the street. Yes yes, on the street, if you make my almost imperceptible movements, what I do because I play a lot with high sensitivity in FPS and I need a very high accuracy on the small clearance pointer to remain accurate, the mouse will not detect and / or make leaps !!! A peak when one needs for responsiveness and precision ... In addition, it blocks both, does not want to turn to one side or the other as if it came to a stop the offending side. And it is not at all new mouse mat that is the same brand: Razer Vespula.
FYI I had before (and I still have) a logitech MX518. 2006 if I remember correctly. I find it hard to accept having less accurate almost 8 years later ...
