    Bought for my elderly 85 year old father-in-law. Excellent picture, easy to use, easy to set up. Non-smart TV which is why we bought it.

    The bargain for this TV is nothing short of amazing. I purchased this tv for less that $150. It lacks smart features which is actually a selling point for me as my primary tv's both have them, and neither of them are satisfactory to me and have added Roku's to them to supplement missing features. This TV was purchased for use in my bedroom, it makes a great secondary TV. Picture quality is good, sound quality is good, no in depth set up needed. I've had numerous insignia tv's in the past, one of them is still working and it's 12 years old. I'm hopeful that this one will last just as long.

    I purchase this TV for my son for his dorm room. It worked as expected but this best thing about it was the light weight. Very easy to move around and the picture quality was pretty good for the price.

    I purchased this tv after my old 32" started acting up and have not been disappointed so far. This is my first Insignia brand and I thought that I would give it a try after reading a lot of the amazing reviews on this product. The 1080p picture is awesome and I can actually hear the audio through the built in speakers, which is a nice improvement from my smaller tv that I previously used. Think it could benefit from a decent soundbar, but it does sound good. If you are just looking for a 1080p tv that is not a smart tv, then I would definitely recommend this best buy brand.

    I bought this tv because we have a large covered backyard patio and wanted to be able to watch TV and movies outdoors. I didn't want to spend a lot of money on a TV that would be in the heat (AZ). The picture is very good and we use a Roku stick on it to watch movies. It is a great bargain and performs well for the price.

    We were looking for an inexpensive TV for the bedroom. This TV was moderately priced and offered free shipping. I set it up and let it run for 4 days to make sure there wouldn't be any immediate problems. It has a clear picture with good color and works well with our Roku.

    I am very pleased with this TV. It is mounted on the wall in the kids room. The picture is great and it is easy to operate. The size is perfect. I have had no problems at all with it and would recommend it to anyone.

    A good, basic non-smart TV that works perfectly in the bedroom or as a smaller living room TV. I was impressed with how easy setup was and everything worked well. The picture is also pretty good for being a cheap option.

    Bought this as a replacement bedroom TV and it is great. Picture is vivid and the sound is good....esp since it's a bedroom TV I don't need loud volume. Easy set up for one person....who's not a techie. :)

    Good TV for the money

    I usually get "name brand" TVs but I've been impressed with Insignia on some recent installs I've done using the 19 and 24 inch TVs as security monitors or auxiliary TV's. When our Toshiba broke from a flying Wii remote, I purchased yet another Insignia. My only issue has been that I have an additional 24 " on a swinging arm between the Living room and the kitchen and the remote occasionally turns the wrong one on or off.

    We purchased this tv for our basement to use while we are walking on our treadmill. We are very happy with it. It was easy to set up, has a great picture and good sound. Works well with our roku that has the remote with tv power on/off and volume controls.

    Bought as a basic tv for grandma. Picture was clear for her and easy to use and fits nicely atop her 36 width dresser. We purposely chose it for the stand since we couldn’t mount this on the wall.

    The picture and color depth on this TV is excellent, even in eco mode. I was not going for a high end TV because of how and where I Had intended to use it. I was shocked as how great it was for the minimal cost. I have paired it with a ROKU and I could not be happier.

    Insignia 40" not a smart TV

    I like the older style remote (with number buttons). The picture is great and it makes one heck of monitor for my laptop. I was surprised it uses more electricity than the 43" TV I have (40W compared to 28W) but it is an older model. Setup was easy.
