This keyboard is built great, the design is magnificent, the rubber dome keys make little difference outside of the fact that you won't be able to use a full set of custom key caps
That said, the key-sticking issue has NOT been solved after 6 months, It is likely that it will never be fixed, as it is a design flaw based on the USB'NKRO matrixing implementation.
THE KEYBOARD is completely motherf!@#% useless....
At first, I was angry, then they promised theyed fix it within "weeks", then they said, sorry we don't know wtf to do, I rma-ed twice, then they gave me a K90, but guess what, the K90 ALSO has the Key-sticking issue, WHICH IS ALSO unfixed after 6 months
Imagining racing or playing a game, and a key like the space bar gets stuck, it does't get physically stuck, what happens is, even when the key is released, the keyboard still thinks it's depressed.
The corsair forum below is the primary thread for this rampant key sticking issue, confirms UNFIXED for 6+ months
