so far pretty good
I have only used it for less than a week, but it works perfect. It even survived a bumpy 2 day ride in a uhaul trailer! The remote (comes with batteries) and tv have lots of useful features (roku controls, sound bar controls, program guide, favorite channel, etc) the picture is excellent and the sound is good for my purposes. I will soon connect an android box to make it the ultimate smart tv. At $279 for a 4k tv, i'is s a great deal.
