I bought this tv due to owning Vizio tvs in the past and the great quality I had with them. This 70 " is great when watching my movies along with my surround sound system is almost like in a movie theater. The only thing is I can't add apps to it to watch more or listen to more that I do on my fire stick. This is another reason to get a smart tv was to do away with the fire stick but I had to connect an antenna to the tv to get my local channels. Other than that it is great.
Let's start out with the very positive . . . overall we're very pleased with the purchase. The picture and sound quality are excellent. This is the second 4K UHD TV we own, the other being a Sharp. Comparing the two pictures, although they are both exceptional, I'd give a slight edge to the Vizio. The colors seem more vibrant and the images are very sharp. So why not a 5 ⭐ rating? Twice now the TV has stopped recognizing the remote ( . . . both the Vizio and the upgraded Roku remotes) and once ( . . . so far) the entire setup process had to be redone from scratch. The TV had to be unplugged and replugged in order to get the remotes working again. It worked but it's a brand new set and we shouldn't have to worry about things like that.
Would we buy another Vizio??? Absolutely. Would it be the only 4K UHD TV that we look at??? Absolutely not. But it would absolutely be in the running!!!
