Summary: This items arrived broken, screen apparently had suffered damaged in the shipment to my home. HOWEVER, my local Walmart in Berlin Vermont cheerfully exchanged the unit with no questions asked. They did not, however, have a duplicate replacement so I had to upgrade to a larger set for $100 more. Overall, I was very happy in the smoothness of the replacement transaction.
Summary: This is just a plain old LED TV, nothing special makes it worth over $500. No internet capabilities, poor sound quality and a limited ability to extend its capabilities. I returned it after finding a Vizio for less than $100 more that has all the options and picture quality that Samsung's Smart TV's have. Samsung has a bad habit of farming out its screen production.
Pros: This TV Looks and performs nicely. At the time I bought it, it was a great 1080p display for its size and price.
Cons: If you care about image quality, don't plan on ever watching interlaced video on this unit. The built-in de-interlacer is horrible, makes the picture muddy and grainy, and screws up the contrast big time. I had to reconfigure my satellite receiver to output 720p since 1080i looked horrible.
