Approximately one week plagued me after unpacking the keyboard rough exhalations. Even headaches I got, even though I never really have a headache. The stench has then but -glücklicherweise - warped and now I have at my work a keyboard, provides everything that I've tested / possessed in the shade!. Since I am a web developer, the keyboard is almost my main work equipment and accordingly the requirements are quite high. The Apple Keyboard meets all - perfect pressure point, ideal feel and a magical sound. It is worthwhile for anyone who works on a daily basis in order and will not connect Windows keyboard to his beloved Mac (-> I use a MacBook Pro).
