Unfortunately, very, very noisy

I mostly use the "Rain" or "Rain O²" settings. And right there is also my criticism. The "Rain" setting provides a beautiful, gently falling spray pattern and is very pleasant on the skin. However, the shower is unbearably loud. For me showering can mean just also relax, and this really fits such a noisy shower not now. The strong noise caused at the turbulence of the water inside the shower head. Therefore only a "satisfactory" from me.
