If you buy the Chromecast, you have to be aware of how this works. You can transfer content from their smartphone or tablet to your TV here is not easy. The stick can rather only retrieve content from the Internet and then play but these problems. So you send from his smartphone so for example, only a link to a youtube video and the stick then loads this from the Internet and does not this the smartphone. Thus, the drive also needs necessarily an Internet connection via WLAN. This concept is not bad per se, but has the disadvantage that just a handful of services are supported. Eben as indicated: Google services such as YouTube, Music and Videos from the PlayStore. In Germany also Watch Ever is now available, making the stick for the customers of Watch Ever really interesting. But as I just Amazon Instant Video famous and this just is not (yet) supported by this stick, this currently is not a perfect solution for me. Since Amazon is probably imagine the next few months your own streaming stick or a set-top box, it is questionable whether Instant Video will ever support Chromecast. Technically that would be readily possible to implement just have you look at it. The price, however, is still hot for what the stick can and there is hope that a lot more services are supported, such as Spotify. For 35 I can just barely live with the limitations, but let everyone decide for themselves.
Conclusion: For the price a good device, but with very many limitations.
