Now the device: Unlike to be read here, the installation ran without any problems. The wifi connection could be established within a few seconds the Speedport router. The connection is very stable and fast. I use the device mainly for max cathedrals. And it runs great! It starts quickly, all functions can be selected quickly, as I'm used to it from a 2013er Bravia.
The look like me. What do you want because for about 100, - expect more? And if Amazon Instant Video should run well, then there are 5 star.
Addendum: Since 12.4. now works Amazon Instant Video, so I was able to forgive even the last star.
