I've owned multiple Sceptres and the only thing that ever broke for me was button related (on both the remotes and TV itself). You'd think buttons would be a solved problem, but I've owned three of those TVs because of the price (SmartTVs were not universal then).
That all being said, the displays themselves are mediocre and the speakers are weak and poor quality. The quality is probably right in line with the price, but if you're coming from a higher end TV, it will be noticeable. I always had to use speakers or a soundbar to get acceptable quality sound, the display you get used to pretty quickly.
Assuming Sceptre still makes dumb TVs by then, I'll probably switch back to them when mine either die or LG crosses some red lines.
