Despite gas water heater is still working properly and there is not a big delay in adjusting the temperature felt.
Of course, the pressure is not as strong as in other shower heads, when you hold it horizontally, the water injection no 1,5m wide. But I think that's not so bad, Special thereby rather less water bib. Who, of course, expect a massage jet, should resort to another product.
The workmanship is very good. The water jet can not be adjusted, but that is indeed apparent from the description.
Even with the volume: The shower head is through the addition of Luftblässchen actually a little louder than my previous showerhead. This I feel personally but not disturbing.
In any case, a clear recommendation for bargain hunters and environmentally conscious!
