The shower can be installed very easy, after some in the shower hose inserts were inserted in order to reduce water consumption. Then you have the choice between two modes. A shower mode where the water comes from the pleasant shower head, and a "cleaning mode", where the water shoots in strong rays from the center of the head and you can not so pleasant a shower. Switching between the two modes is very pleasant with a small handle on the showerhead, so you do not need cumbersome am actually turning head. Overall a very pleasant shower head, with the showering fun and hopefully water is saved. I can only recommend.
