Great picture, quality, connection, and easy to set up! Picture Quality Great picture, no lagging at all so far! Clear with vivid and great colors. Sound Quality Lower volume options is even loud enough. No issue with static or muffledness...love Samsung brands. Design sleek, good size for a smaller room but big enough picture even for a decent sized room. Performance So far has worked out phenomenally! Used to watch Netflix on my tv or through an older version of the roku and there was times especially when trying to watch in hd the video would lag and regardless of what I did wouldn't be normal for more than a few minutes. Such a pain!! With my new tv...runs perfect. Don't have that problem anymore! My only complaint so far and not sure if that's because it is only a few weeks old and hasn't become "smart enough" yet since it says it gets smarter the more you use it...is that in order to connect to like Netflix for example...you need to turn the tv on and let it sit for a couple minutes before it officially connects. I only use the tv for internet mainly Netflix purposes so it is a little bit of a pain. For those who don't mind being a little patient though can't complain much! Overall I'd say a great buy and for an amazing price on black Friday!!
