I have a water heater (one floor below in the basement) and have to say that this shower head with relatively little water but produces a very decent jet.
Unfortunately, this shower head is repeatedly dropped mainly well my 12 year old daughter (yes dear children), and the last drop of the shower head is broken at the foot down. Regardless, he has the last 3 months, dripped on the head a little, and the beam was not as clean as at the beginning when I bought this.
After the first defect before about 8 weeks I have ordered these saving showerhead due to the customer reviews:
PSC = 1
Here the shower experience is but a completely different. A very soft beam with plenty of air perhaps his followers, but does not find us in the family. Now we have decided these aforementioned shower head again to order and now look forward to when I again meet this hard jet :-)
As I said this shower head is designed for cables with relatively little pressure and does in these circumstances really a 'pressure Full' shower experience.
Let's see how long he keeps this time, I will report ...
