The Chromecast is a good idea and it works. Contrary to the list of Google, he also works with my Fritzbox 3390 without any problems. Although, unfortunately, but that harmless not in the 5 GHz range but only the 2.4 Ghz band. Although the WiFi does not bring optimal transmit power (only 2 of 5 bar) which is due to the installation site of the Fritz box; streamt he easily everything on the TV what he gets fed. As output devices, a Sony Xperia Z2, a Xperia Tablet Z and a Samsung Galaxy S3.Verbindungsabbrüche or errors serve there have been none.
Picture and sound are perfectly acceptable and it is to be hoped that the Chrome Stick is further developed.
