17 buttons to tame!

I had a Razer DeathAdder, which I was quite satisfied (a mouse of the same brand, a little larger, and 5 buttons).
But as I play various MMO, I needed to have more buttons.
I bought the naga, and sensitivity level, no complaints, it's niquel. Razer quality. There's even software that can record macros in rows and retrieve them on another computer for those who travel and have no desire to reconfigure everything.
Besides, I think, there must be a configuration session, as well as 12 buttons on the side are pre-configured, configuration is not helpful. sensitivity and acceleration of the mouse are also set at the beginning.

After 17 buttons, at first, it's really weird. It takes getting used to, and it is not instantaneous.
But once mastered, the 17 buttons provide a really fun game intense.
Do not be discouraged at first because you are unable to use buttons.
