Have done to my Microsoft Surface me the German keyboard. Finally my Surface has become a right Ultrabook. The keyboard is super comfortable, high quality, and a thousand times better than the strenuous touch cases, I used previously. When I joined for the first time, only worked the touchpad. The Greek Seller responded very quickly and very nice to my questioning mail and tried to give advice. The proposals from the Microsoft support helped not. I had a RESET (recovery) perform, but in which all the apps and all my documents were preserved. Since then, the keyboard works perfectly.
