Hello,
I have the same problem. I contacted the support and they replaced and like the others, after 1 month the new one is failing too.
It seems like its related to a lag between the mouse and the OS.
I'm just testing in windows paint clicking and seeing if dot is printed.
If I click fast, sometimes the dot is not printed. And I noticed that when doing long click, sometimes there is a delay between the hardware click and the dot being printed, like 500ms. And I assume that when doing fast clicks, this delay is just cancelling the click.
What shall we do now ? We keep replacing the mouse every few months ?
Does corsair is even interested in our customers ?
