Awesome product!
Ok so I was skeptical at 1st with all the mixed reviews but I finally decided to give it a try. Let me start off by saying this you will have to do some set up in the settings as all tvs are different and to get the best experience it will take some time and patience. After about 30 minutes of moving the towers around and tweaking the settings I finally got it working right. I am very satisfied with it as it makes watching movie so awesome. Some colors don't match up perfectly but as in shades of colors. I definitely recommend this to anyone that wants to take movie nights to the next level.

Love, love, love!
The kit is easy to install and set up. The only installation note I have is of your TV is not perfectly flat on the backside you may need to get creative when attaching the rope lights. Our TV is a 55in Amazon fire TV and because the back slants a little we had to be very intentional about where we placed the clips but in the end everything worked out.
Functionally, these lights are great and the camera does a good job reading the screen, however, we do have a ceiling light directly above our TV and if it's on the camera reads the reflection of the light as a yellow color at the bottom of the screen. We tried recalibrating with the light on a few different times but it still gets picked up. Not a huge deal, if we're using the movie mode we just turn off the ceiling light and everything works great.

Govee TV Backlight 3 Lite: My Movie Nights Just Got a Whole Lot Cooler!
This Govee TV backlight kit is an absolute game-changer! I was looking for a way to enhance my TV viewing experience, and this definitely did the trick. The installation was super easy – just peel and stick the LED strips to the back of my TV, and I was good to go. The app is intuitive and gives you tons of control over the colors, brightness, and even music sync options.
What really blew me away was how much more immersive my movies and shows feel. The lights create this awesome ambient glow that extends the colors of the screen onto the wall behind the TV. It's like having my own personal home theater! Plus, it just makes the whole room look cooler.
I've also been using the music sync feature when I'm listening to tunes, and it's a total blast. The lights dance and change color to the beat of the music, creating a really fun and vibrant atmosphere.
Overall, I'm beyond impressed with the Govee TV Backlight 3 Lite. It's a fantastic product that's added a whole new dimension to my entertainment setup. If you're looking for a way to take your TV time to the next level, I highly recommend checking this out!
