The installation took less than 5minutes.
It reduces the flow exactly to 10 liters!
I measured it with a bucket of 5 liters and a digital stopwatch.
After 30seconds the bucket was full. Here, the tap was turned on to the max!
For the price he has already paid off after a month even.
(You must not forget the waste water costs in the calculation!)
At first I considered myself go up a showerhead of 6L makes minute.
But this would have paid off to use only after more than 4 years!
Would be worth this, I believe only in a 6-person family!
None of us noted at 10L / minute a difference in water pressure or the usual shower Quality!
