    Great price! We use these for security camera displays on either 8 camera or 12 camera display mode. Work really well for large screen security display at affordable price.

    Excellent TV. Very easy to assemble legs and connect to cable box and Roku. I would say from box to watching took perhaps 15-20 minutes. Very satisfied with purchase.

    I bought it for my mother and she loves it. Good quality sound and picture. She hooked up her Roku stick it and loves her setup. I plan on keeping this brand and getting her a bigger size in the near future.

    Got this 40 inch TV during Labor Day for only $100! 1080p screen, 60fps, pretty good sound, and decent color accuracy. This is NOT a Smart TV but for the price, it has been worth it. Bought a Roku Express as well to watch all my streaming services.

    I am more than pleased with this television. The picture quality is outstanding and very sharp. This is not a 4K set by any means but is a giant improvement from my earlier flat screen. The sound system could be stronger and is my only gripe. You can set the TV up in a matter of minutes including linking the cable remote.

    for the price? Great value. Good for a guest room or a kids TV. Dont expect for this to be the great TV in your living room. But for a guest bed or even a main bedroom not a bad choice. So cheap! But well made for the price.
