    We’ are satisfied with the great clear picture. Sound is great without the use of an additional sound bar. Ease of unpacking with the detailed instructions. Very easy to attach the legs/feet. Overall we are pleased with the television!

    I needed a good basic tv to replace a 31" Insignia in the bedroom that was just too hard to see all the detail. This 40" was just right. So light it was easy to mount. The picture is great for me and for this application I didn't need anything higher resolution. Low price was added bonus.

    If you're seeking a "non-smart" TV, this is the ONLY one I've been able to find that doesn't have Google, Fire, Tizen or other "Smart" bloatware. It's Full HD 1080p, not 4K but a great picture.

    Very good picture quality. Light weight compared to my old LCD tv. Store pick up easy. My only regret is not having done home delivery so they would pick up old tv. Now they want to charge me $30 to take it.

    It is good size and good quality for price. Would buy again. Only bad thing is the only button on the tv is a power button, so if you want to turn down the volume or turn it up and lose the remote you have to figure that out.

    Tv is perfectly fine.I thought it was a smart TV from what I read online and was disappointed when it arrived. Have to use streaming box so that's inconvenient but of no fault to television itself. Good picture,nothing fancy.

    Purchased this model as a Mother's Day gift to upgrade my Mother's bedroom television. She likes it and says the picture is clear and she was able to connect her firestick and surround sound easily. Good price for a decent "extra" t.v.

    Thank You BestBuy for the Non-Smart Platform!

    I am grateful that Insignia/BestBuy continues to offer a non-smart platform. I prefer using an external streaming device and connecting via HDMI versus having Smart built into a TV, so thank you BestBuy! The sound and picture for this model is excellent, considering the price. The only con (still not enough to knock it down from 5 stars to 4) is that it has a poor viewing angle. The crisp image is pretty much limited to normal incidence viewing.
