Hello, I wanted to replace my old Michelin-cylinder foot pump with double cylinder CARPOINT. What a mistake! -> The pump is wobbly (1 cm difference between the 2 feet) -> When setting / removing the system from the valve a lot of air is lost -> The graduation of the pressure gauge are too coarse (in bar) and not detailed enough. One of my Michelin pump is much more readable and is more serious. I returned to the CARPOINT get a refund.
