I ordered the very expensive shower fitting and the matching Nobili Loop washbasin fitting from a German wholesaler. At this price, I expect very good quality. But far from it: at the shower tap the hand shower and the shower head of the rain shower are made of the cheapest plastic - because I get better products in the hardware store at a much lower price !!! Despite rework / replacement of the inner part of the shower fitting is still dripping. I am curious if the next repair will be successful.
Furthermore, the topic times for delivery and repair (s):
I ordered everything on August 7, 2018 at the German wholesaler on site. The shower fitting was stocked here - so no problem. The basin mixer should be delivered directly from the factory in Italy. With company holidays and lost package, I have finally received the basin mixer MITTE OCTOBER.
My conclusion: poor quality for an overpriced price and zero service - never order anything here again !!!
