M65 rgb middle scrollwheel too hard to click?

I just bought my m65 rgb for 3 days, at first it works fine. But now the middle scrollwheel only registers clicks when I press so much harder on it. Does anyone have the same problem, my finger is so tired:sigh!:

Might be a faulty mouse wheel.

 

I would contact your seller and ask if they can replace it for you. If not, request an RMA to replace it via Corsair.
