Thanks to the Hemame the purchase decision then came to such a pass, and I can only confirm this. Woman gets ball, woman can again sitzten and woman and man happy!
But the men of the round. Strong lungs need you! While it is supplied a pump. This is for the rough work Top! But when it comes to the pressure, only helps lungs work. Since the pump simply has no power. My wife wanted the ball is then fixed, so I solved the hose from the pump and blown into the tube. (Caution in sitzten do otherwise is Umfallgefahr, and Blackout)
Now the ball is nice and firm, and woman happy and I can return to normal sitzten at the table.
