Yea some level of quality control would be nice for "PRO" gaming hardware.
Im on my 3rd K70 rgb keyboard and the 3rd one has the same miss colored/unlit keys as the first 2 i just gave up on RMAs and now my M65 has the missing/double click issue
So im looking at a 100% chance Corsair products Will FAIL!
its a shame because they look great and seem to be built sturdy but my record and a quick search shows they are plagued with the same repeat issues
