I bought this pump for long motorcycle trips so I have along anytime something which I can set the correct air pressure in the tires and also can check tire pressure. It funtioniert super good. The only drawback for motorcycle operation that can be difficult to get to the valve with the part because it is a bit big. An extension cord would easily solve this Problme I also worried me, and thus the connection of the pump and the Ventiel goes much easier. Why only 4 stars.
