Hello. A colleague wrote me the way he bought it and quotes it. "I was afraid of this brand for a long time, because of popular products such as Samsung or LG. I was looking for a TV with android but ordinary without additions (webos, tizen), I wanted to hook up anything apps and have channels from the net and succeeded. Only on regular Android you can freely modify and add applications from Google play and other systems are stripped down. In addition, I received 4 USB inputs. 3.0 beautiful HDR 4K image. For all these options in competing models was about 1 thousand higher !! and the lack of a USB 3.0 port and the constant thought whether USB 2.0 material from the USB stick will go in 4K! There is even support with a keyboard and these 10 bit panel these colors fairy tale !! Summary: - buying 4k tv to netflix (TV series, movies) and watching 4k (UHD) materials on this tv or other but 4k makes sense - but if someone is buying 4k tv and watching whether digital Polsat or NK + do not count on upscaling, because he will see lower quality because it is only full hd let him buy a full hd television because he will pick it up better. I bought it and got everything I wanted, including wifii, quad core, android, usb. 3.0, 10 bit at the moment is the best choice for 43 inches 4k "
