I have one, took me a bit of getting used to from my old chunky Corsair keyboard, but I think it's a lovely bit of kit.
Is there anything in particular you want to know?
I quite fancy the full-sized version of these (currently using a razer black widow) but... £200 is a bit eye watering. Anything you miss about using a big chungus keyboard?
Gaming on it ok wireless and how long it takes to charge fully.
I fancy the white one.
