Not bad, but a significant weakness

Positives:
Tri Gem LED produced many sharp, beautiful bright light beams.
Number, brightness and color of the light beams are perfectly fine.
The "Sound to Lihgt" - function is also vöiig fine.

Negatives:
The viewing angle is very low, the illuminated area / wall area is therefore very small.
In my 8x5m large party room just the opposite liegene wall is illuminated and not the side walls.
It is better if the light would steered further to the side and up and down would.

Conclusion:
For my 40 square meters large party room not effective enough, so I sent it back.
