Ok, got my Zowie AM today, plugged it in, tried it out, everything seemed great. My aim is way better now that I have a mouse with a good sensor and without any acceleration/prediction. But if I am not able to fix two mandatory problems I will have to return it.
The first is that when I push down the mouse buttons and hold them pushed down, either left or right one, doesn't matter, it seems like there occure little breaks in which either the mouse or my computer does not recognize the signal of me pushing the mouse button down. This leads to a) lots of tks, as I can't time my nades and randomly throw them in front of me, I usually time them so they explode when they hit the floor, you have to keep the mouse button pushed down for that, as sometimes the signal gets lost or whatever my character just throws the nade when this happens, b) I can't properly copy any text anymore, it's annoying as hell.
The second problem is a really strange one, sometimes when I make a movement, not a sudden one, a normal one, my mouse cursor somehow freezes and the movement gets transmitted a few seconds after that. It's not my computer freezing, but simply my mouse. When playing a FPS this is annoying as hell, as I am practically defenseless for a couple of seconds. I already checked if I am maybe lifting the mouse up and this is a side effect of the small LOD, but no, it is not. I use a SteelSeries Qck btw, there should be no problems with it.
Hope you can help me with those two problems, I'd not like to send this otherwise great mouse back.
