Summary: very misleading with the photos. in the photos it shows you getting both the regular key-set and the mmo key-set. i could have just got the keyboard off eBay for $25. total waits of money just for the keyboard.
Summary: I like this KB a lot when Im not using the driver's for it but as soon as I install the driver's the KB goes crazy hitting W open's my firefox menu tab.... The first and last item I ever buy from Steelseries, I gave it to my friend and picked up a nice new razor KB that has working software.
Not compatible with WinXP and can't enter Motherboard's Bios.

Summary: The bad of this keyboard is that it's not completely compatible with WinXP 32bit. I'm told WinXP 64bit works fine with this keyboard, though. So, in short Win7 this board is about 3-4 stars. As for WinXP (and maybe even for entering Bios), I'd say avoid this keyboard.
Summary: I have used a zboard for years. I upgraded it with each WoW expansion. With cataclysm I bought the new keyset, and put it on my zboard. I had to uninstall the zboard software and install the steelseries engine. This took several tries before it took.
