I bought this pump some time ago together with the Royy Toys tankers. First, the pump has to work. But after the second filling of the tank was the pump on their minds. Is a good idea and probably well intentioned from the manufacturer. But the pump is simply bad konstoiert. Since the company Franz Schneider steps still need to rework well. Otherwise the quality of Rolly Toys toys is very good. Not to vertehen why at this pump, the quality is so ill. I can only agree with the previous speakers. Let your fingers away from the pump, it is not worth their money.
