Hey there !
Back in 2014 (23 January), I bought a CM Storm Devastator Combo. I was quite satisfied with it but I have never fully appreciated it because of some minor problems.
Sometimes, the I or Space bar key would stood blocked in pressed position or the LMB would work weirdly or the MMB wouldn't work at all while the wheel would make a weird noise when used. But it happened only sparsely and I didn't find it worth getting a replacement product.
As time as passed, it has gone worse. The I and the space bar still get stuck from time to time but, well, I have get used to it. The worst part is with the mouse. The Middle Mouse Button (The one "under" the wheel then) don't work at all for a few days now and that's quite annoying as the MMB is a button I use a lot ! And if sometime, I get it to work with mere chance, it will triple click !
It's almost two years since I bought it (I'm in France so I bought it from a French retailer) so I probably can't do a RMA but do you have tips that I could follow to try and fix it ? It's a good mouse overall despite it's small flaw and it is a really good gear for this price range so I want to keep it as long as I can but these problems start to be more and more present and really annoying.
