Quite decent for the money. This one is powered via USB cable, the lighting is quite good, and the app that connects to the strip is very well made and easy to use. I wholeheartedly recommend VFM

For its price, it is the ultimate value for money. It sticks perfectly, has instructions, a good app, and connects immediately to WiFi. I don't know what someone would want more than a movie for 5-7€...

On my TV, when I have it on, it sometimes flickers in brightness, but it might be because of the USB or the connection. I will check and get back to you.

Update: Money wasted. I would have been better off burning the money in a fireplace that I don't have. It flickers like a candle flame. It's garbage.

I have stuck it behind the mirror in the bedroom. I use it at 1% brightness and it creates a very nice atmosphere. Obviously, the uses that someone can exploit are countless. What I will mention is that the adhesive on the tape is very good, the connection with the application is very easy, as well as the management of it for scenarios, scenes, colors, etc. Keep in mind that because the company promotes it for use on the back of the TV (Philips ambilight effect), it is powered by USB. The package does not include a USB plug. Obviously, it can use one of the dozens we all have at home from our phones.

It was placed behind a 50" television.
The length was sufficient, as it did not go to the edge of the television frame.
It provides very nice lighting, which makes viewing much more comfortable.
Powered by the television's USB. The only problem is that sometimes it disconnects when the television is turned on (and loses its settings), and the only way to fix it is to unplug and plug it back into the USB.

Update: In the end, I changed the power supply and connected it to the USB of a surge protector. It is controlled through Google Home, and now it doesn't lose its settings, despite frequent power outages and internet interruptions in our area.

The photo is a brightness comparison of this LED strip vs Sonoff L2 Lite (daylight color from Google Home). Sonoff has double the brightness. Depending on usage and location, you choose and get it.

I managed to connect it to the app and then to Google Home in 5 minutes without any problem.
It works perfectly with voice assistant.
Its lighting is okay. It could have been a little brighter. I'm not complaining for the money I spent. I use it behind the bedroom as hidden lighting.
The Music sync doesn't work at all. It just flickers and changes colors without listening to the music. I didn't buy it for that, so I'm not interested.
I have placed it on a horizontal surface, so it won't move. I can't comment on whether the adhesive tape it has is good or not, but we almost always reinforce it, especially if it is stuck to a heat source.
It is the most affordable smart LED strip and it works PERFECTLY.

The purchase was made on 30/01/2022.
I have been using the LED strip for 1.5 months.
It took me at least 5-6 hours to connect it because it is incompatible with some routers.
It only works through 2.4GHz and not on 5GHz.
It does not connect with certain Chinese routers from Cosmote, so I had to find other routers for it to connect.
It is not waterproof.
Also, the adhesive tape, even though it is 3M, is not of good quality.
The entire tape came off and did not stick properly again.
I had to buy new double-sided adhesive tape and reapply it.
Overall, if someone wants to spend up to 12 euros and experiment with LED strips, I don't know which is the best choice.
I want to buy a higher quality LED strip in the coming months.

Quite a quality LED strip, after purchasing and testing the first one, I was satisfied and bought more. The white is natural and the colors are equally bright. The adhesive requires a little attention at the beginning, mine started to come off, sticking to the paper instead of the strip. It connects to 2.4 GHz wifi (not compatible if you only use 5 GHz). The initial setup and operation are done through the Gosund app, which is practically a clone of the well-known Tuya/Smart Life. It does not include a USB adapter, so you need to have your own. If you place it behind a TV that already has a USB port, it will work normally. It connects without any problems with Alexa-Google Home for voice control. Wifi and internet access are required as it operates through cloud service.
