Errr... the build quality for Vizio TVs is dreadful. I had one fail twice in the warranty period and then of course immediately after the warranty expired.
Opening the thing up the mainboard of the device was fastened to the backlight panel chassis with packing tape. I'd never seen such shoddy construction, not to mention the very poor quality of the boards themselves.
In general I think the idea of "smart tvs" is bad for the consumer economically. On top of that selling our viewing habits a profit center for Vizio on their already crappy throw-away TVs. And to add insult to injury, the UI for most smart TVS is just terrible. I replaced the Vizio with a Samsung, not because I wanted another smart tv, but because it was cheap. Not only was the search function hopelessly broken, the damn thing interrupted stuff I was watching on Netflix or Amazon with service change bulletins for Samsung services I neither subscribed to nor used. How could any UI designers be so damned stupid.
But you almost can't get a smallish HD TV that's not "smart". I ended up with a Hitachi "Roku TV" which is just a plain old TV with a Roku stick stuck in one the HDMIs. I'm much happier with Roku's UI and service, but if I wanted to I could just pop the Roku stick out and have a plain old TV.
