I had my eye on this keyboard for quite a while. My son got one and loves it. My old keyboard started to "catch" slightly on a few keys, resulting in more-that-usual typing errors and some irritation.
I was sold on the Corsair brand and the Cherry MX Brown keys for quite a while. I wasn't so convinced about the need for RGB lighting, but did want some lighting. I'm a touch-typist, but as the hands go from keyboard-to-mouse and back, it can be tricky to find your place again in the dark, especially if you are just looking for a single key.
This keyboard rarely goes on sale. I assumed it would during the Thanksgiving season, but it didn't. Fortunately, a couple weeks or so into December my patience was rewarded. It was on sale at Best Buy, but was also a few dollars less at an online store. Best Buy cheerfully matched their price. Yay!
PRO - Very nice feel. Very consistent. Nicely adjustable RGB lighting. You can be overly fancy, or very simple. I don't need waves and ripples of light, but I did customize it a bit by making the numeric row, the F and J home keys, and the arrow keys a bit different from the rest of the keyboard.
CON - Even though Cherry MX Brown keys are not "clicky," there is still a fair amount of clatter while typing. I plan to try a set of O-rings that should help dampen that. There are some basic "media control" keys, and a nice roller for volume, but I was surprised at the lack of "special function" keys for things like launching the Media Player or the Calculator and stuff like that. You can program the F-keys, but some applications I use rely on the Function Keys for special shortcuts, so it would be silly to override them. I could program them unique to each application, but that's more than I want to bother with.
It could also use a couple more lights to indicate status, such as if you have pressed the "Insert" key that changes the way you insert or overwrite text while typing.
Lastly, the software for customizing the keyboard is bizarre! It took a lot to figure out. Not for the timid, that's for sure.
OTHER - I think a Cherry MX Clear switch would be perfect for me. Just a bit more resistance while typing. But they are nearly impossible to find, and when you do find them, they are expensive. Overall, the MX Brown are working out well for me.
