Good for: Someone looking for a good value in a 55", without spending more than $400. Someone who wants 4K with HDR. HDR has better brightness and blacks than a regular TV. Built-in Roku with 4K and HDR support. Can stream movies, shows, and music directly on the TV. Can fully control the TV with the Roku app on smartphones and tablets, including turning the TV on/off. We owned this TV since December, and found it an excellent value. While the HDR is sharp and a noticeable upgrade over 1080p, other TVs will have better HDR, yet they cost $600+.
Also, the TV feels like it was made with flimsy plastic. Do not lift the TV with one person, or keep in a place where it can be bumped.
