We have the LED ball for our party room (30 sqm) purchased and installed on the ceiling. The lighting effects are absolutely great and cover the entire area. The operating noise, a slight hum is not disturbing, and goes completely around volume under. Deduction is only because of the announced Lichtorgel effect does not work properly, at least for us. The device will only respond to very loud sounds, and is otherwise dark. But this can also be due to the ball in the middle of the room, the speakers are mounted but in the margin. We let the ball just run on continuous operation, which also interferes with anyone. From our side, despite this small flaws a strong buy recommendation.
