Simply put, once taken the habit of media keys, the keyboard is impeccable. The connection to the PC via the key is done without any difficulty. The least: I was hoping to configure the buttons. Impossible (Trust and France confirmed it). Thus, no copy / paste possible on the 2 side buttons (but "previous / next page"), no double-click on the dial. Disappointed, because I planned really find the functions I had on my old devices.
