Pro:
-Very good / accurate tracking without input lag.
-rutschfeste surface.
-liegt comfortably in your hand.
-clear defined pressure points and reliable mouse wheel.
Cons:
-Irgendetwas In the mouse is loose and klackert with fast movements (SteelSeries Support has not yet responded, and this problem have many)
Lubricates driver for firmware updates mouse often 1-2 times now and makes the mouse up to a completed update unusable (So a second mouse for the case at hand and hold)
-If Angle Snapping and Deceleration (re-acceleration) are activated, the mouse is almost useless, since it jumps and no longer rumzickt only with very fast movements. (Maybe it's for me a individual cases, SteelSeries has not yet responded)
All in all I am satisfied and, despite her weaknesses only recommend the mouse.
