I just bought this TV. I was surprised at the picture quality and the sound quality. It took me 10 minutes to set up and start using. TV comes with a voice remote that I really haven't had to use yet because the buttons are so easy to use. For the money it is a perfect all-around TV.
I learned about ROKU a couple years ago via my adult grandson who had bought one for his bedroom. So ,I bought 3 for my retirement apartment. (for 2 bedrooms & a living room) I liked them so much (NO expensive cable TV subscription was necessary) that I bought my new Series 4K 50" ROKU for my bedroom in my primary residence. I LOVE IT! Easy for a Senior (age 81) to use, and the sound is terrific as well as the picture quality. Now, I am the proud owner/user of SEVEN ROKU TVs in our 2 homes (living with my spouse, an adult grandson & his 9-year old daughter). I LOVE ROKU!
