So I bought the Razer Lycosa about 1 month or so ago, as I wanted a new gaming keyboard which at the time seemed like the right Idea, but it's just not working for me as good as the Logitech was.
I'll weigh the pro's and con's and then you can tell me which you think is the better option.
Razor Pro's:
* Keys feel nice to type on as they're rubberised. (non-slip)
* The blue LED give the keyboard a nice feel to it.
* The touch screen media keys are nice.
Razor Lycosa Con's:
* The keys become unresponsive every once in a while, so I have to unplug and then plug it back in.
* The programmable keys on it are awkward and you don't have seperate keys to program.
Logitech G15 Pro's:
* Very nice keyboard, well set out, nice size.
* 8 Programmable keys with G1, G2 and G3 so that's 32 programmable keys.
* Type on the keyboard feels nice. (not as nice as the lycosa though).
* LED screen which can be useful during gaming, showing cpu temps, speeds, processor usage and so on.
* Nice media controls, not touch screen, but amazing none the less.
Logitech G15 Con's:
* I've lost the leg stands..
* I've lost the arm rest.
* The keys aren't rubber, which makes them not as nice to type on.
* It's a bit dirty and needs a major clean and that'd take a good while
