    Needed a tv for the bedroom and this tv was a good price and offers a good picture. Most flat screen tvs have poor sound do I didn’t even wait and purchased a small sound bar. It was icing on the cake that the sound bar was on sale. Overall - It does the job.

    Suited my needs perfectly both feature and price wise. Have bought several Insignia brand items over the years with zero issues. Didn't need a "Smart" TV where it's going. Hooked up a Roku device and DVD player. So good to go!

    Hey, for the money — it’s fabulous!

    In terms of size, color, clarity — great screen!! It’s hard to quibble, but the remote didn’t sync up with my Cox account. (My problem? Maybe, but it sure wasn’t obvious.) Once you turn the TV on, it seems ridiculous to reach for one remote for the sound, and the other to change the channel, rewind, FF, etc. I like the # of HDMI hookups in the back too.

    Works perfect! I needed a non smart tv for my father with dementia. He can work it, picture is good, sound is loud enough for him. I couldn't of asked for a better tv for him!

    Upstairs needed something and this was it! Perfect for us sports fanatics so we don’t miss a minute of the game. When you have to move spaces, nice to turn this on and continue.

    My bedroom TV died so I went to Best Buy to get a replacement. The sales associate Alex helped me pick one out that was Roku ready. (Because I already had Roku.) I thought my old TV was 40 inches but when I got my Insignia TV home to my delight it was bigger than my old one. The picture quality is excellent. I LOVE my new TV and recommend it to all!
