After a long time I came back to test for a long time the SS Rival. She had a partly better sensor in contrast to other mice. The handling conformed to time (Use the Finger Tip Technique) and I'm really pleased with the mouse.
All in all I can only recommend this mouse :)
UPDATE: It's really so annoying that I mostly just with the mouse or mouse wheel get SteelSeries mice defects. In my 3rd (!) Rival here the mouse wheel is again broken. It hunkelt and jerky to himself. It is sometimes loosely fixed sometimes. Quality control seems SteelSeries probably not giving ..
UPDATE:
This is now my (!) 4. Rival mouse. In the beginning (about 2-3 weeks) I thought it was finally the right, the mouse wheel bombproof and the sensor makes no problems. But now the sensor is catastrophic. I really only play CS: GO and have a low-Sens players (400 dpi and in the game 1.3), which means I have to make fast mouse movements, however, the sensor has probably avoid problems if I go too fast on the pad disfiguration Crosshair (or mouse) immediately upward. This happens more often even though it went without any problems at the beginning.
The processing of the mouse is still really bad. If I here read how many people own a problem with the mouse wheel have (I had) I wonder really whether it something like a quality control are at SteelSeries .. The mouse is really very good otherwise, very handy and has a good sensor ,
