Mouse issues.

[Obscurity]

I have a corsair M90 mouse (MMO gaming mouse, yeah yeah )
It used to be wonderful, has loads of different buttons that I have a bind for, and they used to be super super responsive. But lately they have become disgustingly unresponsive, only picking up the input sometimes, or having a big delay between button press and actual input. I'm not sure what could be causing it. Everything else about the mouse is absolutely fine.
Has anyone experienced anything like this before?

i have the M60 & have had similar problems , unfortunately found no answer .
also i am overall not impressed with the mouse , although it looks & feels great i get a lot of mouse acceleration when trying small movements ,& and trying to update the software is a nightmare .
after 6 months i am now going to replace it with another CM storm sentinal

you had a look to see if there are any firmware updates for your mouse?

It sounds to me like its more hardware related than software so a FW update might not fix it, its sounds like it could be just down to wear and tear so unless your good with a soldering iron then maybe a new mouse is on the cards.

I've had the same mouse since January but luckily no problems yet. How long did you have your before it started to have flaws?
