    TV has a good quality picture for it not being a Smart TV. Plugged in my Firestick and it’s just as good. Only thing I don’t like is the sound volume on it. But otherwise is is way worth the price

    Excellent for the price, perfect to play videogames that do not required 4k resolution. And the fact that is not a smart TV makes it more convenient since you don't need to be updating the TV or be connected to the internet.

    Fairly good value for the price. My son wanted at least a 1080P tv for his room--hooked up a cheap antenna and he has over 30 free channels. It is not a smart TV so if you want that with this, you'd have to hook up a roku or something, not a big deal for us. Picture is decent, sound is as always on the cheaper TVs, not the best so he hooked up some amplified speakers--works great.

    When my old tv died, I knew Best Buy was the store to shop to get the best price for my $$. I shopped around hoping I was wrong but I was right, no other store has what I wanted at the low price I paid. Setup was easy with no difficulties and all you needed was a screwdriver.

    Hook up a fire stick or a Chromecast and you are all set to have an excellent TV experience. Picture quality is amazing for the price and it sounds good too. I bought it for my kids to play Xbox but now I think I should have just bought this for our tv room instead of the expensive Samsung.
