I have had it for 6 months, satisfactory image, relatively easy to use, very poor sound, goes up and down by itself.

Just purchased, what I was afraid of was the slow software, since a few months ago, my mother-in-law bought a Samsung (not an Android TV, with Samsung's software). Terrible software, a very slow TV with a slow processor and costing €450 as she told me. Buying this specific TCL from a well-known department store for €399 from €409 that they had, I really didn't expect such a good processor and quite fast. It was worth the money, the picture is commendable for its price, the black is not black, if you want something in QLED or OLED with good black, go there because you'll be disappointed with the black from this one. The sound is just good enough to do its job. The remote control is very good, the buttons are of the type that will last for many years, shortcuts for several applications. Now to mention its negatives, there are some things in TCL's apps that I don't like, I wish it had pure Android inside and that's it. The remote control also has a microphone for voice search and you don't need to shout at the TV, and it's Bluetooth so you can change channels even if you're in the attic. I bought this one for my father, replacing a 32-inch one that he, due to his age, could no longer read the subtitles and wasn't enjoying TV. Now I saw him in great joy and he told me, finally, I enjoy watching sports and movies.
