ZOWIE FK2 Mouse for Esports White Edition

How do you change the LOD (Lift Off Distance) setting of the mouse?

Is there any reason why my mouse doesn't work well on the mousepad I am using?

In the game, when I shoot and try to swap weapons with the mouse wheel quickly, it won't register the movement when scrolling.

The mouse works fine when moving up or down, but when the mouse points in any other direction, the sensor lags, stops entirely, or moves at 1/3 speed. What should I do?
