Solid 4.4+ stars reviews (140+ people) in Amazon. The TV by itself is very good.
This is an outstanding 1080p TV.
I bought one new a month ago ($1600 in BJ Wholesale Club, the same price as Amazon) otherwise I may had snagged this refurb here at woot. (I have several woot refurb projectors and they have worked just fine). The only problem ever I've had with refurb was with an Apple ipod right here in woot and I would never do that again. The TV sold last year for around $2,000. It is cheaper now because VIZIO came out with a 240HZ model.
I don't usually care about additional features on a TV but this model is very handy watching Netflix, Amazon etc on the tv just by flicking a button on the remote. NO need to switch to a separate box.
Since it runs at 120Hz video refresh, you will probably want to adjust the settings to avoid having movies look like tv soap operas due to the "smooth action" algo - It's a personal taste kind of kind. Some folks love the "extra clear look", I prefer my movies to look like movies including filmed TV series. You won't have to call a professional, you have access to many options right from your remote and if you read the reviews at Amazon and other places you will see folks list their favorite settings. Initially I left mine as it came, but after a week I played with the settings to tune it to my liking, including removing the smooth action. The remote control itself is smaller than expected but if you flip it over it has a keyboard. Comes in handy typing in the wifi password, searching netflix, amazon, etc.
Angle wise, some reviewers complain about NOT being able to see it from the sides, we havent had that problem. It replaced a Samsung DLP which could be viewed from many different angles but this is the same, if not better. We have it in a room with an L shaped "pit" furniture and a huge ottoman in center and it is equally enjoyable anywhere on the room.
The picture quality is very bright (can be toned down or up at will) and can be very vivid or subdued (again based on your taste). Very good blacks and dark areas on the screen. I know some people complaint that LEDs can't come close to PLASMA TVs but this one is close enough for anyone less than a purist.
The built-in sound is good considering there is NOTHING to this TV. Meaning it has a thin (one inch or less) "frame" around the screen like a picture frame, so the speakers face backwards (mounted behind). This actually makes the sound bounce back at you from the wall which surprisingly works out fine. I prefer deeper/louder sound so I have it hooked up to a receiver, but I sometimes I don't turn on the receiver and the kids often use it without the amp. It depends on taste. Via the amp the surround sound is as rich as any other quality source. Without it is fairly loud.
If you are mounting it on a wall, make sure to get the right mount. And if you are not, make sure you push in the included base tightly against the TV and tighten the four screws "in sequence" (like replacing a tire). The TV is huge and the stand is tiny, so you want a nice tight fit. I'm using it on a glass stand I had and I found it best to open the box upside down, and apply the base while the TV was upright (vertical) upside down looking down on it. Gravity helped sit the base in nicely.
In terms of size, if you have a 60 or 65 inch Samsung type DLP TV, the 70 will fit in nearly the same space because as I said earlier it is just the screen and a thin frame around it- no extra plastic.
I'm picky about large TVs, taking me a while to find one that I would like at a price I feel is fair and this TV is very nice all around. I would definitely buy it again. You can not get a better 70in TV unless you pay an additional $800-$1,000 and considering how quickly the technology changes, it wasn't worth it to me. But even if you do pay more, I'm not sure many people could tell the difference.
We have an 11 foot screen "movie room" in the basement but this TV gets a lot of attention right in the living room. People see it and are drawn to whatever it's playing on it. Fantastic purchase.
