    Great Bargain

    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.

    We have several insignia TVs and this is a great value. It’s large enough to hang on the wall in the bedroom and the perfect size. Great picture and value for the money!

    Love the TV. We have a small living room, so it's just perfect. Sound is really good, bot we route it thru surround sound speakers. Picture is great. I have not had any issues with it, just good quality tv. Would buy again.

    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 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.

    Very cheap but good for the low price. Sure its not bright enough for a sunlit room but you wouldnt expect that at this price. Its got decent brightness still though, and the sound is good too. Picture is 1080p which is good enough at 40 inches. You cant see the extra detail of 4k resolution at 40 inches unless you're very close to the screen so i didn't care to spend extra for a 4k tv at this size.

    For the price, this is an awesome little TV. I purchased it to mount onto a wall in my bedroom, and it is the perfect size. The display is great, I only use it to play video games, and it does the job perfectly. Very happy.

    Great picture and sound, Make sure you set the sound to TV if you are not using anything else as Auto can cause the sound to cut out. Easy to setup too.

    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.

    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.
