Well, the film is very high quality and useful if you choose it for the right purpose. The main reason that makes it value for money is the connectivity it offers.
If you want a simple LED strip to enjoy in the room or for intense lighting to replace a regular lamp or just for simple decorative ambient lighting, then in my opinion, you will be wasting your money on this one.
The reason I got it is for its compatibility with Razer Chroma and also for mild room lighting. It gets a 10/10 in both aspects. The network connection was relatively easy and I haven't encountered any problems so far (the network is of good quality). It has enough cable length before and after the switch, so installing it away from the power outlet is easy.
I was impressed by the construction, which seems quite good. It is indeed waterproof, although it wouldn't be a good idea to put it in the shower, but if it's under the desk and water spills on it, nothing will happen. Its response is immediate from any application you use it with, which is quite impressive if you want 30 colors changing per second along with your other peripherals or if you have set it to respond to the sounds playing on your computer.
It is also convenient that it is simultaneously connected everywhere, meaning that when it is connected to Chroma but not being used by the profile, you can simply control it from your phone. The application that needs to be downloaded for the computer is a simple bridge that runs in the background and you forget about its existence.
As for the negatives, I have to say that there is no possibility to control each LED separately (which is expected) and the only way to extend it is from the end of the strip, while there could have been additional ports on the switch to allow for expansion in different directions.
There are many people who say that it doesn't have true white, and they are right, but this is a detail that is not noticeable when you don't directly look at the LEDs, meaning how you would use the product on a daily basis. Is it really RGBW or just RGB? I have no idea, you can see for yourself and decide. Personally, I don't care much. One image shows the white produced by the application (more blue) and the other image shows the white produced by Chroma with RGB-255 values (warmer color).
Update: In this particular strip, the slight current is not liked. When it is turned on, everything is fine, but when you turn it off, it makes a small static noise that you may have encountered in other electronics as well, so because it is installed in a bedroom, I have to unplug it every night.
