    Very straightforward TV. Take it out of the packaging safely, screw on the stands (or wall mount if you have one), and set up the TV then boom. Easy as that. HDMI and Cable (if you have it) channles are easily accessible through the "input" button on the remote. Very simple, good quality tv for the price as well. Do not buy if you plan on getting a PS5 or Xbox Series S | X. Find a 4k Quality option instead.

    Great purchase. I couldn't believe how light the TV is and the picture is even more impressive. The delivery was fast and it arrived in perfect condition. Absolutely love to purchase my electronics at Best Buy.

    A great unit, good size, fantastic picture, and so vivid. The sound is a LITTLE bit weak, which can be mitigated by turning the volume way up, or adding a sound bar, which I did, via the output jack... no big. I’m quite satisfied with this tv, and you can’t beat the price!

    Great tv for the price. Just buy any streaming device, connect it to one of three HDMI ports, and presto! you've got a 1080 smart tv. You can always connect an antenna, too, and watch free tv. Audio not that bad, but you can always add a sound system if you want. Remote easy to work and menu simple and straightforward to navigate. Heck, if you need a wallet friendly 40 in tv for a small living room, this Insignia brand HD tv wouldn't be a bad way to go...not bad at all...

    The insignia is a great choice for the extra bedroom or kids room. I selected this model because of the price and at the end of the day the quality was dead on as well.

    I am so satisfied with my purchase. The colors are beautiful. I did not realize going from 32 inch to a 40 inch in the kitchen would make that much difference. The full HD is great.
