Fancyleds for life!
I’ve bought the first gen and now I’ve upgraded to these because I bought a new tv. They work the same if not better. Since these are RGBW the color on the leds are more accurate and somehow pop more. It’s on the expensive side but very worth it works great with ps5 and Apple TV, switching media is easy with app. The app works amazing too very easy to setup.

Best LED I’ve seen
Such a better product than the Govee. Bought TWO defective Govees, then tried this and it was easier to install, looks better and has made me very satisfied. 10/10 looks great

Fast react. Love it
I have a 98 inch and I knew I would be short on led but was a lot shorter than expected. Still was able to use it. Mine is not wall mounted so I did not go all the way to the bottom of my TV. Works great!

Not worth the price.
Lighting is only good at night time and you get use to the led within a month or so. The hdmi port pretty stupid and won't auto switch port like it supposed to. I usually have my pc on first and sometimes me or someone else would accidentally bump the ps5 controller and turn on the console. It force the hdmi port switch to the Ps5 console and stay on that port only. The app or physical device can't switch back to the PC. Turning off the ps5 doesn't do anything too. Only fix is to turn both pc and ps5 off then turn on the PC again. It only saving grace is that the rgbw react ok with any games. And yet it still mess that up.I use a red square on my desktop to test the rgbw tracing and fine out that the rgbw can only track colors to the correct corner only. When I move the red square to the bottom of my screen. The rgbw glow red on the right side of the TV. Up goes left, right goes down and left goes up. Honestly I could have run everything to my pc and have the PC controller the rgbw and it would of done a better. I can see this going for $200-$300 for a 4 port hdmi. But $500 and it doesn't work as advertised is just a scam.

Meh, very disappointing not worth it
Idea is great but there's huge lag and several times doesn't even match the colors, I tested with some videos and if you pay attention is way out of wack.. video won't upload but here's a quick pic that doesn't do justice but oh well hopefully you'll get the idea. I guess I'm one of the NOT lucky ones lol definetly not like the youtubevideos you see. Not sure if this unit is defective or that's just how it is. I had purchase an extra led strip from them and it's the same, not happy. So to sum it up it's not worth it, I regret buying it.

Beautiful and accurate.
A year later and this thing still works great. Love the colors and the performance.

Great LEDs
Excellent product. Bright LEDs and easy setup. Really adds to the experience when watching sports or a movie. I really liked the corner pieces that allow you to securely bend the LEDs around each corner and make it look nicer that the competitor’s products.

Comparison Fancyleds, Govee, Hue
If you don’t mind having to use an app on your phone everytime you need to switch between devices, then this is an excellent choice! CEC / AUTO SWITCHING HDMI Highly annoying as the device claims to be CEC compatible, they just don’t have it implemented correctly. There are certain things you have to manually program with CEC to make it user friendly; their programmers clearly don’t know about this. If you follow CEC strictly, it kinda sucks for actual usage. For example, most people don’t turn off their apple tv (which with CEC would turn off your tv as well) before turning on the game console. Well strict CEC implementation won’t switch to the game console because the previous input is still sending signal. They need to program it so that regardless of previous input, when it detects a NEW input signal, it switches to that hdmi. Now many hdmi switches will also send a CEC off signal to the previous device, to help with switching back to that device. That part is optional, as it can be annoying for gamers when they accidentally click their apple tv remote while gaming and the console shuts down. Govee also fails to implement CEC, and even worse than Fancyleds. The only brand to make CEC right is Hue Sync Box. GOVEE Overall quality is worse than fancyleds, AND may be more expensive. Worse CEC, worse LED density, worse light reproduction… but maybe better app controls. HUE Best quality in CEC and light reproduction in their new 8k model; but awful pricing and the fact that you have to buy the LED backlight separately, AND power it separately is annoying. I like just plugging the light strip into the sync box like the other two brands. I hate how bulky hue gradient strip is, and also the power plug for the strip AND sync box both just annoy me. I do like a clean install and Hue fails this metric. SUMMARY If fancyleds would improve their CEC programming beyond just basic specification, they would absolutely dominate the market of hdmi based backlighting. I’ve written them about it, but to date i get idiot replies about how they support cec and i should reboot my devices (facepalm). If their devs read my comments they’ll realize what I mean, it’s a stupid simple adjustment to their firmware!
