highly recommend roku

Great TV and an incredible value. I wasted a few thousand dollars on an OLED TV a few years ago. It had a lot of burn in and the colers were all off. Please don't waste your money on an OLED. This TV has great color and brightness and we enjoy watching it. The TV is thin, so the surface isn't as flat as the more expensive solid glass panels, but I am done wasting money on high end TV's. I also really love Roku. It is easy to use and I like the simple app grid. This is my favorite smart TV platform. Overall, very happy.

Very surprised buyer, I like it
I am a big Samsung user. I like the Samsung app. However this TV is very good and uses many traditional apps like Roku. The price was fantastic so I expected a crappy TV, but I was very surprised. It was easy to set up and I would definitely buy more of these in the future. The television turns on quickly, faster than my Samsung. It also changes channels quickly. The television turns on quickly, faster than my Samsung. It also changes channels quickly. fYI, my father owned a TV store and I grew up around them so I am very picky.
