What is it with the spacebar on this keyboard. It is absolutely the worst I've encountered. It works fine for a short while then it becomes all wobbely and makes weird sound when clicking. Ive removed it and checked. Everything seems in order. Is it a design flaw? I have problems wit my M65 Elite mouse too. I thought Corsair was a quality brand. Is it?

My M 65 Elite doesn't register all mouse clicks either. How big is the problem with Corsair mice and the buttons? It worked fine for about a month. Bought it this spring. But maybe two months ago I noticed that it didn't register all my clicking. I've tried reinstalling firmware and moving it to another USB port but it doesn't help. Quite annoying. Had Logitech nice for a very long time and this was my first non Logitech mouse. Maybe I'll just put it in a drawer and by a wireless G502?
