First of all: class device! The battery life is totally OK (have it more often when grilling on the terrace) and the sound for such a compact device with battery and electronics on board is really good! If it is on, it is usually found immediately from my iPad or MacBook and if the stream runs is really very rare to short dropouts which I suspect rather my Wi-Fi and / or iPad / MacBook here. So be it! Why the star deduction: It switches itself off automatically! And this is not it! When he is not on the terrace it stands as streamers in the kitchen and often I will hear music while cooking and then I have to turn on only the device, then wait until it has booted or connect to the Wi-Fi has, then he has just been are recognized and only then can I select it in iTunes and connect and finally listen to music. By comparison, the bathroom I have a Philips device are that is permanently connected and I can hear music ... even more beautiful almost immediately!
