Hello There, the pump does not deserve the name. It is therefore not to use such. I wanted my trekking inflate wheel and already the second pumping test, the chants has bent. The quality is lousy. I have now bought a hand pump for 30 EUR, which is very good. Apparently you only get junk for less than 15 EUR and must invest more halt. Since I got my money after intensive mail traffic as well as the return shipping costs amounting 4.10 EUR there is a star for the service of ZBP. For the product Zero stars.
