A few days ago we have this in fact send hand shower installed in our shower, here are suggestions for improvement:
Please extend 1) the handle - so the hand shower also a (large) man's hand,
can accommodate without contact with the tube, and thus "it" of (very)
can speak more comfortable handling
2) the keys to select the spray jet, mounted on top of the
Effervescent likely, can be pressed easily and quietly while bucking less
3) as eyeglass wearers would also I liked that the selection of
different spray programs not alone through tiny lettering, or
Test run, it can be seen, but distinguished for example by tactile symbols
can be.
I bottom line improvements as these "little things" and classifies them not want to hang up, I would give the effervescent prefer 4.5 stars out of 5.
