After living with it, I wouldn't recommend the Corsair K70 RGB if you were sold on the LED aspect. I'm sure the key switches could very well last longer due to how they are made...however, unless the room is very dark, their illumination is almost pastel. It's not very bright. I would say to find another model, or wait for v2.0.
Also, all of their marketing stated that there are 16.8 million colors...but this is not the case. The demo units showed incredibly smooth color shifts and brightness adjustments, but the production model has proven to be much more limited. There are visible "steps" from one color to another, even when your program specifically just calls for a smooth shift from one to another, with no programmed steps in between. The same holds true when dimming them. I tried making one look like it was "breathing" but it looks like how old NES games used to fade to black in their cut scenes (steps down in brightness).
I also really don't like the rubberized wrist wrest. I would much rather have had it be hard plastic. I use this keyboard for hours and hours every single day...I couldn't possibly wash my hands enough to prevent shiny spots on the wrist rest.
Lastly, I don't know what it is about this keyboard, but I'm CONSTANTLY hitting the caps lock key accidentally. Can't figure it out.
Oh, and I can't really hold it against the keyboard because this isn't meant to be the programmable multi-function model, but I do miss having a calculator and shut-down key like I have on my other keyboard.
