I got a 9008 from pchome a while back.
I had issues with the spacebar registering double presses. Fixed this by resoldering the join.
It then developed issues with the S key doing the same thing. I'm going to go out on a limb here and say that I'll fix them when I resolder the join...
Quality-wise, I would say they feel like a cut above the old logitech/microsoft type ordeal, but they aren't quite as heavy and robust as some of the older mechanical boards I've used (Model M, Apple Extended II etc), or is the build quite as good as the Razer BlackWidow I use at home (although to be fair it's not much worse).
Overall, I'm not entirely happy, but having said that, I'm not entirely displeased either. If they had better QC, they would be very awesome.
