Honestly the thing just lit up and the waves are made so that you do not recognize how the pattern repeats. The colors are beautiful set. After eingier time it turns out then while you're asleep. So perhaps for children. For adults it is too light to fall asleep, so rather for romantic moments. But then you have the choice between red / green / blue or mixed. The built-in speakers is rather expensive nature and the power cord is a bit short. The LEDs used are optimally strong, that's what counts. Since everything is made of plastic I gave only 4 points in durability, so but I think for the money that's all fine. What I'm missing is a mode of much slower changes between the colors - so almost imperceptibly. There is something, but the change it as fast for my taste.
