This is a great 4K TV for a budget price. The picture settings out of the box aren't the greatest and made me worried at first, but once you play around with the picture settings (i.e Backlights, Contrast, Sharpness) you can really make the picture quality look great. Now the only problem I have with this TV, is that anything non HD looks pretty damn bad. 1080p and up looks great, 720p looks good, but anything below that just doesn't look good at all. The built in applications are pretty good, Netflix and YouTube are the main two apps, and they work pretty well on this. The audio is also better than I expected. For the price I bought this televison at (£369), I would say that it was worth the money for such a good looking 4K televison, which also has HDR! Don't be put off by the less well known brand, this TV is great.
