Note, Electronic Express has some poor reviews (and here too), so this deal is a little risky.
If you're willing to spend more for less risk, Amazon.com sells it for $20 more plus tax.
This TV has been our recommended pick for best value since 2017.
Its HDR picture gives vibrant colors and deep blacks, and its built-in 4K Roku provides streaming video directly on the TV.
It can be fully controlled by the included remote and the Roku mobile app.
As many reviewers also say, it's a great TV but not the best... a sharp picture but not as sharp as TVs that cost twice as much.
It's not the best quality (some people had bad experiences dealing with TCL support), but most people had no issues.
Our TCL 55S405 has been mounted on the wall of our living room for the last year and a half, without any issues.
