A4tech mouse doesnt work on A4tech mousepad...

That... is sort of hilarious. But ok, I don't mean to laugh at your misfortune. I'm assuming it works on other pads but not the a4tech one. May I ask, are you located anywhere near their HQ? You might have been able to walk in with the rubber X7-200MP & demand satisfaction, possibly even got a chance to thwack the CEO upside the head with it like a flounder.

Alas, is it possible your mouse no likey rubber mousepad?

Edit: Then again, what envy14tpe wrote makes far more sense, as I've never encountered such a problem, if your mouse is working within an OS, it'll find traction on just about any surface, even if not ideal. But the idea of you thwacking mousepad upside head of CEO is still more humorous imho. Otoh, it sounds as though it's worked on other pads on the sys you're using just not on the rubber one? I dunno, now I'm actually curious to see how this turns out.
 


Welp thats kinda weird idea, but okay 😀
Also the problem with mouse is kinda weird, this mouse have problem to move on mouse pads from "rubber" but when i use it on somekind of magazine it works good.
