I play World of Warcraft frequently, so I bought this and the Wrath of the Lich King insert.
Bad mistake on my part.
If you are unsure what the Zboard is, it is basically a keyboard without any keys. The keys are part of inserts that can be changed depending on which game or game type you are playing. A great idea in theory.
However, after about 2 weeks of using it the S key stopped working. Oddly though, when i took the keyset out, the rubber button that is the S key works just fine. Put the WotLK insert back in, and it stops working. I installed the latest updates and messed around with the settings, still wouldn't work. I put the bog standard keyboard insert in and it worked fine. Figuring it was a software glitch, I continued to use the working keyset, and kept testing the WotLK keyset after every update.
I'm writing this as the S key on the bog standard keyset has done the same thing, so after 6 months they still haven't fixed this problem. After looking on the internet, it seems this is a very common fault (although the keys that stop working are different each time, imagine not being able to use your space bar for example), that has been affecting people for over a year.
I've had to go back to using my original keyboard, until I can find something more robust and reliable.
I would recommend to everyone that you do some research before buying one of these.
I wish I had.
