Keyboard very good quality

I was looking for a keyboard that is not too noisy and it is very quiet.
The tape of the keys is nice although I have a little trouble getting used to the ergonomics, we have a tendency to start looking at some more key right on the position or is programmable keys (G1 > G18) but after a short while you get used to
The brightness of the keys is not strong enough yet
The part to rest the wrist and a hard bit low for my taste
The software is suitable even if I find a bit strange as egonomie
