If you're looking at this TV, you're probably like me in that you want to go as big as possible without breaking the bank. Once you go over 70" in screen size, the price curve grows exponentially and the selection (i.e., number of manufacturers) falls off the map. At 70" you can pick from a variety of manufactures with pricing well below $2k. At 80", the prices start in the $3,000's and go all the way up to $6k. There is only one 90" TV on the market and it's around $8k. So, 70" is clearly the sweet spot with 80" venturing into niche consumer market.Having observed the limited lifespans of flat screens over the years, I opted to not go the Sharp-route @ $5k for an 80". This Vizio, priced around $3k, was therefore the winner. I had my reservations about Vizio - as a brand - because of past experiences with my Vizio TVs. However, in the recent years, many folks have expressed that Vizio has tightened their quality control. So, I took the plunge and picked up this 80" non-3D model.The first TV arrived in good shape. After about an hour of viewing, I noticed that the backlights were horribly uneven. On the left side of the screen, there were vertical bars that made the screen "appear" to have waves in it. It was a mild distraction but nothing super serious (like a cluster of dead pixels). I called Vizio and they said that the light-distribution panels behind the screen were not "glued together" properly which was causing the wave-like effect. While Vizio said it was "their fault," I couldn't help but think that - while in transit - the TV box probably fell down and went boom - causing the panels to separate. Vizio also confirmed that such a fall could technically cause the panels to separate. Since doing a replacement through Vizio would prevent me from returning through Amazon, I opted to have Amazon do the replacement. Amazon, by the way, is awesome at handling the replacements and their concierge team did a fantastic job at handling my case.The second TV arrived about two weeks later. Upon inspection of the box, there was a hold punched in the side and a visible dent on the TV bezel. Assuming that the TV had likely taken some type of fall while in transit, I opted to refuse the delivery and have Amazon send an replacement. On a side note, it baffles me that Vizio doesn't put a little more effort into packaging these TVs. The box is only a few inches wide and there is no type of internal packaging that preserves the screen or bezel from being damaged by a fall or something else striking the outside of the box. I know that everyone wants to be eco-friendly (with boxing) these days but, please, let's find a common ground between efficiency and safety!The third TV arrived about 1.5 weeks later. After the issue with the second TV, I immediately inspected the box and found a hole punched on the front of the box (right in front of the screen). I checked underneath the hole and luckily there was no damage to the screen. We unboxed the TV and swapped it out for the first one. I'm happy to report that the third time was a charm. There are still light distribution problems on this TV but they aren't as bad as the first one. After a month of calling Amazon concierge and Vizio (to set up replacements), I'm just going to stick with this one.In terms of the actual TV, it's functional but nothing special. Per other reviews on related models, the infrared sensor is pretty bad. I'm constantly re-clicking the power button to turn the TV on/off (when the first click doesn't trigger). The interface is also laggy. With a lot of tweaking, picture quality is pretty good but not quite as good as the 80" Sharp offerings. All in all, I do feel that I overpaid to get up to 80" in screen size and the longevity of this set is TBD. Hopefully, when it goes in the next few years, hopefully Sharp and other manufacturers will have more, cheaper 80" offerings available. This will definitely be *my* last Vizio purchase, ever.TL;DR - First two TVs were damaged/defective. The third TV works but still feels cheap.
