Very good equipment
It feels very good in the hand, it's rigid and doesn't make a cheap plastic noise. The key layout is a little unconventional (wider spacing than a conventional keyboard) but it's very easy to adapt to typing.
Typing itself is superbly pleasant for those who appreciate the feel of Chiclet keyboards.
On the software side, I'm a regular iCue user, so it interfaces very well (note that the keyboard can't be configured in Murals in wireless mode, but it works in wired mode). The traditional profiles work in all cases
It's expensive (as we all know, price isn't Corsair's strong point), but it's very pleasant to use, especially when you're working in a predominantly Corsair environment.
