Now with mirroring of smartphone screens 5 stars

Caveat: installation was very easy and quick. Class!
Then an update underwent Watch Ever app on my iPad and already was the "Cast" icon to view. Watching a movie is selected, started on the iPad and then pressed onto the cast Botton about the movie to watch on TV. Result: An error code displayed on the TV. After 20 min. Then found out research on the Internet that Chromecast is recognized as a separate unit by Watch Ever. Since I had an account 5 devices, it came to the meaningless error message. So delete a device from the list, and then it worked fine. Very good! The Youtube app also runs flawlessly.

Now to the reason for my 3 star rating: this is not really a fault of Chromecasts, and represents only a vote for iPhone or iPad users!

I had hoped to be able to be also content browser on the TV show with the Chromecast. If you use the Chrome browser on a PC or Mac can expand this with a 'cast' plug-in. Once you have it installed, appears at the top right of the browser a cast icon which you can press to display the browser content on the TV. And this plug-in, there is not for the iOS. So I can Chromecast (so far) only use it to watch Watch Ever on my TV. I could also already on my PS3 (of course with a significantly higher power consumption). Therefore, I can than iPad users Chromecast only 3 of 5 stars possible.

Update 05/04/2015: there are now (at least for Android) is a "mirror" function in the Chromecast App. Thus the contents of the smartphone screens 1: 1 transferred to the Fersneher. Finally, browsing is possible on TV. Therefore, instead of three now a five-star rating.
