Feels good workmanship, but quickly broken

At first I was thrilled with the shower head, the part acts well made for the price. But now (a few months old) is already something breaks the device, that is one color (blue) no longer works. In addition, the play of colors is almost useless, you always have only red actually at normal temperature, green is definitely too cold for the average German and blue almost even.

The criticized by some noises are audible though, interfere (me) but not because showering is pure in itself for my liking. Perhaps more disturbing, if one is very close under the shower head.
