Now, we have invested in this shower system and the money was definitely worth it! The shower is at two points in the wall tightened and thus holds bombproof. The shower head can be while still move horizontally with the rod and is itself attached to a ball joint. The hand shower served its purpose, but is not often used with us. Switching is done with a knob. This has proved in practice to be a better solution than the previous shower with a push button.
It is also true that the shower head for some time later "wakes up" and a barrage lets drip water. However, the type of construction seems to me, was in the old shower that way.
As a conclusion it can be said that this shower is highly recommended!
