First delivery, in less than a minute it broke. The tire was simply deflating, since the screw valve was loose and losing pressure. The plastic piston disintegrated and it was making a noise...
To the store's credit, they accepted it back and sent a new one. The new one inflated from 2.0 to 2.1 bar and did not increase the pressure further. We are talking about car tires size 205/55/16, not a truck.
In short, with the approximately 20€ it costs, you can use this banknote to light the fire in your fireplace. The 20€ bill would have been more useful.
