@MaximilianKohler I'm sorry dude, I've opened it on my cellphone and then when I moved to the computer I completely forgot! I've read it now and thanks for the input! About the cooperhead, I don't know if I got a faulty one, but when I moved mine horizontally (especially in cs 1.6) my crosshair started going up, and I tried all the cmd comands, mouse fix, etc, at that time. Then I got the 3.0, and man, wonderful! DPI wise, I think that the 400 are perfect for me, don't need more. I play mostly cs 1.6, now moving to cs:go, played a loooong time competitive, still take it "seriously" online, but meh. Currently I'm using windows 7 and overclocking it to 500hz, plan on getting w8, that would be that bad? And comparing the sensors, I'm used to the one that the 3.0 has, to me, no problems at all! I've watched your videos, and it seems that after testing all the other mices, you still preffer the 3.0, is that right?
