Got my panels working again!
Basically, the product is very well made and serves its purpose very well. The lights look nice and fit almost anywhere. Using the app you can control everything precisely and there is even an API. It would be nice if there was a better music scene (Currently the lights react too slowly or not at all if the music is not played louder than normal music) and the price-performance ratio is not quite right - €100 for 4 triangles is a lot. Anyways, I would recommend it a lot and don't think it was a bad decision to buy it.
The installation was very easy. The panels are very bright!
