    Great TV, very user friendly!

    This TV is solid (for someone that doesn’t care much about little details of a TV). It’s easy to get set up, has Roku embedded so I can get to all of my streaming services, and is a good size! Audio and video quality have been good (aka I haven’t noticed issues). Just make sure you look at the product specs if you’re planning on putting it on a TV stand, since the feet come pretty wide on the base of it—I knew I would be cutting it close. Would purchase again!

    The picture goes dark every so often and I will have to unplug it and wait a few minutes to replug the set for it to start working. Well I e had this same exact tv and it did the same thing and eventually the picture just never came back on. The picture quality is decent and it is easy to use and light weight. The quality. I don’t know. I use this in my bedroom
