    Purchased for my elderly father. Picture quality is great and the volume goes high enough for him to hear it. I’d buy this brand for myself too

    Wanted an inexpensive tv for our daughter’s room for when she comes home from college. Hooked a Roku to it so she can stream shows. She is happy. Not the best quality picture like we are used to, but it works for a spare room that is only used a handful of times each year.
