I bought this over the new Vizio M series even though that has HDMI 2.1 spec but a 60fps native resolution. When I first set this TV up, the colors were washed out and I like the saturated colors. I followed TCL "6-Series" 2019 Settings over at rting.com and adjusted the settings more on my viewing preferences.
Personally, I set the color all the way to '100' and turned off all Motion Smoothing settings in the Movie mode. Otherwise, the tv is nice and the design is bezel-less with a silver / 'gun-metal' frame finish.
The remote that is included is only IR and is NOT the RF enhanced voice remote. I have picked up the Roku enhanced voice remote from Amazon for about $20+tax to go with this TV setup will update this once the remote is delivered.
Update: I got the Roku enhanced remote and paired it with the TV. No Issues and works great. No longer have to point the remote in the direction of the TV. In the meantime, the rtings.com review of the TCL 5 series QLED is also out for anyone curious about the full review. I still have my color settings to max. For me, this TV was a nice purchase.
