I was tired of constantly change the batteries on my keyboard wireless original Apple I ended up buying it. It is certainly less than the original class but at least it works when asked! Typing is pleasant. In addition it allows to connect two devices (3 in total) and thus to alternate easily by selecting F1-F2-F3 the desired terminal. So I'm using both my mac mini and my iPad with ease. To summarize I find this keyboard than the Apple keyboard in terms of ergonomics.
