Good thing we have compared

The versions with a flow rate of only 5.8 liters per minute are unfortunately not to use. It is virtually impossible at this dribble to showers. Since even provides a more comfortable camping canister. The water saved is more than made up for by the time penalty for potty training. Instead of "EcoJoy" Grohe should prefer to use the term "EcoJoke" here. For these products there is no serious purpose, except perhaps one wants to wean the showers. 0 stars.

The versions with a flow rate of 9.4 liters per minute already represent a certain restriction against "unbridled" shower heads. The jet's just not quite as cozy-enveloping as usual, but worlds more comfortable than the extreme savings option. To me it was no problem with short hair, to cope in the usual time with a shower. But especially with people with very long hair is also likely to frequent the extra time for rinsing make water savings canceled out. 3.5 stars.
