After the effervescent attach no water emerges at the screw positions the absolute sealing everything clearly is probably the fact is all just plastic.
The shower is not too small, will come in a nice package in even a small water repellent Black bag contained one can optimally inserting for hanging soap after showering the faucet. Otherwise, I think of no reason why the is included.
The Geleuchte I want to call it quickly loses its appeal. There are no sequences, or the like is passed through water rotates the rotary body at the output of this shower and the LED will flash as in a disco.
Random color messed up in fast rhythm.
But what makes me think is that the LEDs are indeed powered by batteries. If there is now a little battery acid leaking what you indeed can not notice or corrode the battery or not well made is what you indeed can not be seen, and then keep to this water mixture over the body, well not so great.
But that is pure speculation but not abwägig.
Even if the Geleuchte is something for you have to know yourself whether you like that can withstand even health.
