Hi,
The 'n' and 'b' key are suddenly dead, even if if unpluged and repluged the keyboard and try from a usb hub and directly into the computer.
My keyboard is approximatly 1.5 year old, I always take care of it and it have a skin on it. Never splill anything on it too
That's the second one that do the same things, but the first one take at least two years before to do it. And it was exactly the same keys that died with the previous keyboard.
I think that there is a coincidence here and that there's a basic design problem.
