Super simple installation of Wasserwirblers and amazing result! Water is much softer and more pleasant to the skin. In our very calcareous water, I always had problems with my hair (get dull, etc.) - Since Swirly I notice a clear improvement .. On Swirly is 'love' and eingraviert- if you believe in it, the water is also this energies :-) So I think on it, and I'm feeling better you when I had showered why not? .... price absolutely fine. Shipping and handling very intuitive + very friendly and quick.
