First and foremost...this 55" is a "beast!"; I had been in the market for a 4K tv for the longest time, in that time I have diligently researched all 4K tv's from 40" on up to 55". I came across this Samsung model and compared it to every other tv in its price range, screen size, & features on hand; and after careful consideration, I knew this was going to be my final decision. For the "price", "quality", and "feature-rich amenities", I was sold on this Samsung 55" inch set. I purchased this in February and I am still just as impressed as the day I bought it. If I had to complain about anything, it would be the generic-ish controller that came with such a beautiful tv, other then that let me "emphatically" suggest this model for your future 4K purchase.

Bought this as an upgrade to a TV I've had for 5 years. And the quality of the product is amazing and is more than I expected. For a smart TV I don't have to use any other equipment to watch Netflix, YouTube or Amazon prime video. And it was somewhat easy to program everything I needed to program. #5stars

For those looking for a very affordable midsized TV this is a great choice. Color and picture are exceptional for the price. 20x better than a 50” RCA that I bought for only $100 the prior year. SmartTV functions have worked excellent so far no issues. Very good speakers on the TV itself although I use a sound bar and woofer with it. Cons to be aware of are the fact that it has only 2 HDMI ports (I was able to make it work since the SmartTV replaced my Chromecast/Firestick) and it does not have a headphone jack.

Ok. I decided to hold off on the review until I had a chance to experience the TV. So here we go. It is a super fast responding television for the class. The smart features are very quick not laggy like the models before in this price range. The picture stays sharp, but there is an issue with the hdmi CEC. It does cause the tv to randomly reboot when a sound bar or controller is connected. It's not all the time it's usually on startup because the sound device will boot before the TV turns on. It's a bit of a head ache when you are trying to have a movie night and you just turned on the TV, but this is avoided by using analog or optical cable, but the sound is very low quality not being processed through the CEC, but all and all the TV is great if I can leave it on and not have to deal with powering on all my devices out of sync. BTW..The sound bar is also samsung..so it's strange this isn't better in-sync.

Great picture and sound! Very easy to setup and connect to Samsung account if you choose to do so. However, you will need a Samsung account to download additional apps.
