Summary: The only reason that am giving this 3 stars is because I had first purchased an LG55lm7600 and returned that thinking this may be the better option. The LG has a far superior picture which is obviously the reason it costs more, but returned it anyway based on the wonderful reviews this TV has. If I had not watched the LG for three weeks, then purchased the Vizio second, I would have kept the Vizio.
Summary: After doing a ton of research on LED televisions, I had decided on the M3D550KD which has raving reviews. However, it's been replaced with a newer model. Better right? That's what I was banking on but have been sadly disappointed. Let me say before going on that I don't consider myself an overly-picky person and don't have a ton of experience with LED televisions.
Summary: I just bought this TV and I must say is has a nice picture but I can't get the Netflix app to stream. I have tried everything and it still wont work. So I am having to use my PS3 to stream Netflix. Very disappointed with that aspect of it. Other than that, no problems thus far.
Good 3D TV, but lacks 2D->3D conversion and poor sound quality

Summary: This is a very good TV for display, 3D display. Sony BDP-S590 is able to up convert DVDs to 3D and about 50% movies are looking pretty well (although the conversion is in within box, with no pop-outs) on this TV. But if you are interested in 2D->3D conversion for on the fly TV board cast or devices like ROKU's output, you may regret buying this. Also for sound, you may need a add at least a sound bar.
Summary: Have had this TV for a few days now and although there are issues you can't beat the price. I've got two Samsung UN55C8000 55" I got two years ago for about $1600 more and yes they are a better TV but I can buy two Vizio's that are of acceptable quality. Got this TV for the kids game room. Some of the Pros: - Decent picture. - Lots of Widget apps for network access. Much better than Samsung. - Plenty of interface jacks.
Summary: Anything less than perfect HD looks bad on this TV. I suppose most folks will not care too much about this, but I still watch some old shows and movies that are not in HD, and they are almost unwatchable. Of course, I know it won't look as good as HD, but this is just ridiculously bad. I do compare the picture quality of this TV with that of my Samsung LN46A950... a TV with the most perfect picture I have ever seen, SD or HD.
Summary: Bought it a month ago. My TV has manufacturing defect with poor design and weak soldering of input RF socket. Vizio did not honor warranty and did not help in resolving this issue. I was offered to do my own research on parts and repair shops. This is their response: "Unfortunately we do not have the schematics to properly determine the issue. We would suggest contacting a technician to inspect the TV to diagnose the issue and what parts would be needed.
