    Upgrade from 49" that was hit by lightning. Great TV, great picture, better sound than my old Toshiba. Plug & Play, everything I could ask for.

    This TV comes on quickly, has a great picture with great color and the sound is really good. With LED and 4K, all for a really low price.

    I mean, it a smart tv. There's a bit of work that needs to go in to the Fire os for tv but its nothing too bad. There's a random update here and there that bootloops the tv but it is easy to reboot. Connectivity is ok, but could be faster. Display lag is terrible, but i don't really game on tv so it's not really an issue. Picture is ok considering tthe price paid.

    The TV is nice. I enjoy the Fire OS for the most part. The voice prompt is helpful at times and sometimes surprising in its ability to know what you are asking. My biggest beef with this TV is you cannot set a time to prevent it from turning off after 10 minutes on pause. It's annoying to have to either unpause / pause again to reset the timer or to have it shut off and you have to go back into what you were watching.

    This set is an okay entry-level TV that delivers a good amazon experience - the remote response is quick, it's easy to configure and customize, and everything just works. That said, the picture was marginal across all platforms, the blacks aren't deep, the colors rarely stand out, and there are too many better options which offer more all-around at this price point - I decided to keep looking.

    Great tv for my guest room, easy set up, it’s just difficult to find an affordable table to fit this size perfectly. I will make my own tv Console table soon

    TV has great sound and a pretty good picture but there are flashes of lights like a shadow or halo around people on occasion. We had a problem with the picture during fast movements like football games and we adjusted a couple things so that got better but then there's still these weird flashes around people at times. This isn't an expensive TV though, so you have to realize that. It's nice for the price.
