Adapter does not fit:
My bikes have all tire valves with French. The more I was glad to have at least not with little good reviews found this convenient pump. Without the pump adapter does not fit on French valves, which creates is too far. The correct adapter is quickly identified. Plugged into the pump, then put it to the valve's. It does not fit properly, the adapter may not be put on really over the valve. And off you go to the pump. With the first stroke the pump valve jumps from the tire. The black ring seal, which once put in the adapter, still attached to the valve. So friemeln again in the adapter. Try again, same result. With 17 trick it works but then: If you press with one hand pump valve including adapter firmly against the tire and pumped with the other hand, creates one to inflate the tire with a few bar. Should this however be inflated at attention, denied the shaky one-handed pump technology terrific. Pump again released from wheel valve - stuck rubber ring again. After the fourth attempt at the first tire, the annular seal has been on a tear.
Restitution:
This I take particular at Amazon just very very very rare in claim - in this case, it was not different. Perfectly - after all.
Conclusion:
The pump is for my application - to refuel a bicycle tire with a French valve with 4 bar air pressure - totally unsuitable. Just scrap, something I have not seen. Either have bad luck and had a Monday product - or one should consider purchasing another pump into consideration. I opted for the second solution.
