Absolutely loving this!
What sets this apart is that it uses the feed directly from the receiver—no bulky camera stuck to the top of the TV like other brands. Setup was super easy, and my whole family is obsessed with how much bigger and more immersive it makes the TV feel. I previously had a similar model from another company, and it was just okay. This one, though, looks fantastic—clean, bright, and way more accurate with the colors. The clip I shared is from one of the best scenes in Game of Thrones (Battle of the Blackwater), and this was filmed at 2 PM with the lights on. It looks even brighter and more incredible in a dark room. If you're on the fence, this is the one to get.

10/10 product
Easy set up, connection was tricky I would suggest being near your router when you go to set it up with Wi-Fi, works quickly and syncs perfectly. Really makes movie nights so much more fun and exciting!

Not for more than 78 inch TV
NOT FOR ANY TV LARGER THAN 78 INCHES BEWARE. My install followed FancyLeds instruction to the letter and was short way more than the reported size of the TV size supported. Contacted customer service and their response is that I mount it closer to the center of the rear of the TV even though i was already three inches from the edge.

Creates an immersive experience
Love it! Adds such an emmersive experience to my tv viewing! I've used others that rely on a camera to mimic the colors, but there was always a delay and if my cats bumped the camera then it threw everything off. Not an issue with this thing, it relies on the video signal from the hdmi so no camera is needed. It was plug and play and honestly exceeded my expectations! This will not disappoint!

Dropping frames with 10bpc color
Almost perfect if I didn’t turn on the 10bpc (bit per channel) color on my PC :( Once after the 10pm is on I started seeing frame dropping by sudden black screen. I tried power recycle, force reset and resetting 10bpc back to 8bpc as other sources suggested. Turns out only the cause is literally the 10bpc, and the 8bpc works well. I truly hope the device can have some firmware update to fix 10bpc issue or just pausing or slowing down ambient lighting change instead of dropping frames as a workaround.

Completely changed gaming for me
The lights were easy to set up and they look absolutely beautiful. Lots of light customization options with their app so I could tweak levels just to my liking. I can’t play video games anymore without these lights, they truly enhance the experience. Movies and shows pop as well. Definitely worth the purchase.

Excelente producto, muy fácil de instalar y configurar, los colores son muy precisos y el costo muy accesible en comparación a los HUE de phillips, no todas las películas lo aprovechan, seria para películas de ciencia ficción y vídeo juegos ya que es compatible con Vrr y allm para aprovechar al máximo el HDMI 2.1.

Die LED Box haben wir an unserem LG B1 77 Zoll verbaut. Weiterhin ist die Box in der HDMI Schleife zwischen TV und AV Receiver. Technisch funktioniert das erstaunlicherweise mit allen HDMI 2.1 Features. Die LED samt dem ambilight Effekt sind gut - sehr gut, bei Funken Szenen flackert es manchmal, was mit der Speed Einstellung in der App auf 1% nahezu ausgemerzt ist. Die Helligkeit haben wir auf 55%, damit es sanft und angenehm hell wirkt, ohne zu betont zu sein. Die Farben sind stark, Abstufungen erkennt die Box gut. In manchen Szenen hat er problem mit gelb bzw. grün, beides zu unterscheiden. Insgesamt nach so langer Zeit hinterlasst es aber einen tollen Eindruck.
