The only thing I did not like so much: The Chromecast is always "on". It is powered by its own power supply (micro USB) with electricity and feels always warm, even if the TV is off. This is me at the present time but then two star deduction worth.
If anyone knows how to turn off the Chromecast, I am grateful for an answer :-)
(So now I do not pull out the power supply and normally do so on ;-)
