Purchased my 55" OLED A80J a week ago. Enjoying it very much. Easy to set up and use. The picture is outstanding. It upscale HD 1080k to 4k, very impressive. The app's on the TV is great. No need to purchase option streaming boxes. The high speed wireless WiFi make the 4k streaming smooth, providing you have a fast internet connection. The sound is also surprisingly very impressive. Also like using Bluetooth headphone or Wire headphones. This is helpful when not wanting to disturb others in your home.
