    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!

    Excellent TV for the price. Doesn't come loaded up with "smart" features that will be outdated in a couple years. Connecting to a basic Roku device that can be updated every few years. The functionality and configuration allows for all the configuration that I wanted. Picture quality is plenty good and bright.

    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.
