    Great 1080p 40 inch TV for a good price. I needed 1 for my room and this is perfect. Only downside is you need to get a roku or something because it isn't a smart TV but the price makes up for that. No problems with it so far.

    It’s been 6 months so far ! I never turned of the tv and it’s still functioning. Great size for the bedroom, just make sure you get a fire stick or chromecast from Best Buy for the tv

    This is a very good "no frills" TV. I bought it for my mom who is a senior citizen and I didn't want something that would be too complicated for her. The picture and sound quality is very good. I only gave 4 stars because of the remote. We used an antenna and got most of the local channels but because there isn't a guide button on the remote she can't see the channels available or what's playing on them.

    Inexpensive yet still has a great picture. Perfect for an old guy to watch football. Our first smart tv, great to be able to get the prime video Thursday night game. Our son did the setup, it's good to have smart kids.

    I bought it for my cabin it works great for a good price. It has a good picture I didn’t need a smart tv because I have a roku and a Apple TV. My favorite thing about it is it has 3 hdmi ports one being a arc so it worked great with the sound bar I got for it. The speakers don’t sound great but no new tv has good built in speakers. For the price you can’t beat it.

    Never bought a TV through the internet before so I had reservations but everything worked out fine! The TV arrived in great shape and works fine. I wasn't familiar with the Best Buy "Insignia" brand but the picture is great - comparable to the previous Sony TV. I run the audio into my tuner/amp from the headphone output so I can't evaluate the TV's sound quality. For a hard to find "dumb" TV it's excellent.

    I have three Insignia TV's . They last a long time and when it's time to replace one the price is reasonable. If we could only get decent programing for family viewing.
