I could take the device with a friend under the microscope and I can say I am thrilled. The image is incredibly good. The sharpness and the colors make everything pale previously seen. The sound of the built-in speaker is really outstanding. This sound quality so far I could hear with anyone yet another device. The coupling with the Smartphone works without problems. What is still missing is sufficient media to support the 4K technology and fully exploit. The design and build quality are absolutely sublime. One does not have to feel a cheap device in front of him. Everything is very high quality and very well made. - Whoever wants to buy a new TV and the high purchase price is of secondary importance, in this device can definitely strike without hesitation. It is armed with the device for the next year prepared readily. Toll what has made Sony here on their feet!
Update: I came today to enjoy in this fine specimen of television to see a 3D movie. I would recommend that anyone who has the chance to do it the same to me. I've never seen sharper 3D! My Wishlist for Santa Claus needs to be updated immediately ;-)
