Have the unit today given by my wife birthday get (here on Amazon grkauft). Very fast delivery by the dealer. Have the unit directly unpacked and tried extensively. I for one am totally thrilled by the Orbsmart 400. The device has a very good sound (of course, these are not Bose, JBL and Beats by Dr. Dre speaker, because you alone for such a sound already can / have to pay several hundred euros ). But this device is not intended. But the speakers are built to make a pretty good sound. Music over the Internet radio sounds just great on. The display is great (very hot) and the colors are beautiful again. With the included remote control you can run the device to control virtually completely. The unit was charged after unpacking already about 75% and I have 2 documentaries of 45 minutes. viewed on the ARD Mediathek app and a little internet radio heard until the battery was then completely empty. Think that's fine. It should anyway be in the kitchen and there it is anyway plugged into the wall outlet.
My conclusion: A great device and a very strong buy recommendation. Can not fault it :-).
