Fantastic bargain TV
I wanted a basic TV to stream things on . This was surprisingly a great TV . Set up was within a couple of minutes and the picture quality is fantastic for the price . Sound system is good right out of the box . The main reason I purchased this is because I’m sick of other brands pushing their brand to the front of everything and just making it difficult to operate . This TV is so basic and the remote literally has only a few buttons . My other requirement was the TV depth as it was going to sit on an antique easel . This fit the bill and was a bargain to boot .

Solid, well built, TV,
A good value for size and features. Though it's not QLED or highest, newest model, We replace an old tv that glitched out and loaded very slow, so it feels like a big upgrade to us. This also feels like a physically solid and well built TV, unlike many of the bargain brand TV's that are infamous for lasting less than a couple years. Thank you BestBuy for the opportunity to share my review.

Just the right size for me
Easy setup, it started talking to us as soon as we plugged it in. Excellent colour. I like Roku and have been using Roku for years now. Sound quality is better than the last two GE Roku TVs I have owned.
