The shower head is perfectly fine, and costs only a fraction of the original head (65). which is certainly not equivalent: plastic quality (black, not white, maybe not quite bisphenolfrei, etc. ?? - you drink after all the water out of it!) aerator from plastic, is not so much hold (but you can descale with vinegar without rauszuholen it) otherwise everything easier in the inner life.
but I am completely satisfied with price-quality ratio.
