The air cylinder is made of aluminum and looks quite stable, but the fold-out handle looks like as if he would soon bless the temporal ... to open plastic and quite wobbly one at that.
As Luftdruckmesser a Simple device is mounted on the pump, similar to the display of a pressure cooker (with increasing pressure in a cylinder a small pin high)
However, the whole is not suitable, read precise air pressures and makes a inflate only after feeling possible.
For my purposes, the pump already tuts probably, though - their processing demand not too long. One can only hope that the pranksters leave from the station in the future the air in my tires.
