I have tried it already, it has somewhat nice rubber dome and the product page said that it's more durable than treditional rubber dome too.
It has on-the-fly macros, media keys, all of those good stuffs (except LEDs). But I think the macro keys are a little awkward to press. The keyboard itself has a pretty solid build.
The keyset are changable for specific games like the older Zboard with nice improvments, maybe the only board from SteelSeries that have macro capability

black domes FTW lol!
software-wise, in the vid above they said that the software of the keyboard can even suggest you to remap the keys! My crappy Lycosa now looking so dumb!
