    • An Amazon Jewel!
Style: TV only
Yet another reason to love amazon. If you have internet connection, you can free yourself from the cable vultures who keep jacking up the bill with no warning or permission. This TV with built in fire and Alexa will save you so much money because there are plenty of free channels movies and content. I discovered prime video NFL as added bonus! The setup for this system is so easy and has an app for your phone too. I was watching the TV in 15 minutes! The voice remote is incredibly smart and will connect to whatever you desire . You can also subscribe to many third party channels very easy. I cannot say enough about the sound and picture quality being so sharp and brilliant! The only negative I could say is that the remote is very small and can be easily lost so I purchased a backup one just in case. I really am happy about this TV system and wish I bought it sooner. An incredible value!! ... show more

    • So Far, So Good!
Style: TV only
I hate writing reviews so early on a product that has yet to be fully tested or used but so far, so good. I purchased two of these as an idea for computer monitors and they have been working great! The colors are vibrant, the picture is crisp & clear and the functionality (for what I’m using them for) is smooth as I had hoped for. So far I’m happy w this idea and purchase and they look great at my desk! ... show more

    • Can't beat it for the price
Style: TV only
I gave this 4 stars but for the price it could be 5. Picture is good but a bit dull. sound quality is adequate, but a sound bar can fix that. Now I just have to see how long it last.

    • Perfect For Bedroom
Style: TV only
I tried to be a person that didn’t have a television in the bedroom, but I decided to be done with that ideology. I got a 32 inch Hisense TV, and it was fine, but it was too small. I returned it and got this one and WOW WOW WOW. I’m impressed! I’ve never had a QLED TV before, and I’m typically more a of a sound person than visual. I watched Godzilla (2014) as the first thing on this television and it pulled out SO MANY NEW COLORS! That movie is usually too dark even at nighttime, but this television made it seem bright! Very happy with this purchase! ... show more

    • OK but not great TV
Style: TV only
Unfortunately, most manufacturers don't put their top of the line features into smaller TVs. The space we had available would only fit at most a 40 inch TV, so this "quantum dot" model seemed to be the best solution available. The picture is good, but I don't see a big improvement in color or brightness due to the quantum dots over a regular LCD TV. The viewing angle is reasonable, but the picture fades a bit at extreme angles. It's only Full HD, not 4K, but that's not a big deal with this size screen. The TV has two small legs for support, which may not work on a narrow base. I mounted the TV on this swivel tabletop stand, which was easy to attach and works well with the TV. The Fire TV software is not great. Often some of the apps get stuck in an endless buffering loop, even though we have a 1Gbs internet connection and the TV is right next to the Wi-Fi 6 router. Generally, restarting the TV fixes the problem until the next time, usually every day or two. It does interface with the Amazon Fire TV Soundbar using the eARC port and an HDMI cable. However, there is serious lag on the volume control, making it difficult to adjust the sound to the desired level. Overall there's not a lot of choice in this TV size category. If you can fit a 43 inch or larger TV, you'll get much better features. ... show more
