Since I was by my last Logitech keyboard at the end very annoyed, I wanted it once with Microsoft trying (I already had the Arc Mouse, which I was more than impressed). The keyboard came in a huge box (probably because of the irregular shape of the actual packaging), a bit strange, but it should not interfere further. During commissioning, but then the disappointment. Only every second keystroke has been registered, therefore completely useless. The mouse plus extremely unwieldy. So the set went back.
