Seller was contacted, provided free of charge a new pump mechanism. Now everything works.
For product:
I like the design incredibly happy.
Actually, there's only one thing to note: The pumping mechanism does not seem particularly high. In addition, the dispenser part is above rather than metal, such as a suggested picture, but even cheap plastic with metal optics.
For the price I complain about not because the price-performance ratio is okay. But there is one star deduction.
