Good morning. I have connected the film to televisions using the USB that comes in the package. After several days of use, changes, etc., I have the following to say:

In terms of positives, perhaps the only thing is the beautiful brightness it emits, which enhances the space. I notice that now I can see the screen better, more comfortably than the absolute darkness I had before installing it.

Now, onto the negatives... where do I begin? On a previous Sony television that I first tried it on, it did something tricks that may have to do with the infrared, resulting in it shutting down and not turning on again, requiring me to unplug the television for it to work. On another brand new Sony television, it produces an annoying sound in 2 out of the 4 operating modes. Additionally, while the television is turned off, the film suddenly turns on by itself, plays for a while, and then turns off. The keyboard, on the other hand, is all over the place. Some buttons don't work at all, while others have a different function than what is indicated. As for the adhesive, if anyone manages to keep the film stuck for a long time, please tell us the method!

Conclusion: I don't know if my film is defective or if the same thing happens with other similar-priced/category products, but it has many issues, even for its low price. However, I will try some other similar ones in the future to have a more comprehensive picture. I hope I helped.
