The best TV brand
I have TLC Roku tv’s in my house. Only tv you are able to watch spectrum cable without the cable box. I love that you can stream so many free channels. You can also have Netflix, hulu, paramount youtube so many more apps. Easy to understand remote control. I started buying TLC Roku TV’s almost 6 years ago. They are all still perfectly working. I have never had an issue. I highly recommend this brand and this TV right here.

Now our preferred brand of TV
This our our second TCL TV and my son has a couple of them including one in a poll barn that gets frozen in the winter and endures the summer heat and humidity and is still working after a couple of years. Some TVs skimp on ports where as this one has 4 HDMI ports. We used 3 of the 4 ports. Great value for the money . This is now our preferred brand of TV
