I purchased this TV as an upgrade for our living rooms aging Samsung plasma and I'm glad I did! First, you are not going to find a 4k HDTV at 65 inches for this price so I took a chance and picked it up. Set up works flawlessly and I have paired with a Yamaha 4k receiver as my driver (directv and Xbox one plugged in to the receiver outbound goes to the Vizio). Once I got the directv configured to max resolution (only 1080 on my directv box), I started playing with the Xbox and blue rays - all I can say is the screen really pops and the enhanced definition shows me what I've been missing. I have not dived into the apps and steaming options yet but overall I am very pleased with this TV. The only negative I could see for some is the remote is pretty spartan, and the instruction manual seems to focus only on the Visio apps and pairing with your other WiFi enabled devices like your phone or tablet. If you have basic knowledge of hdtv's and have a 4k receiver that can really make your audio pop, this set will definitely put a smile on your face. If you are more app and streaming focused, then you might want to look at other options. Either way, for 700 bucks you will be hard pressed to do better.
