Input:
The ball seems fine, but the pump is junk. The rubber gasket inside the tube is the wrong size for the plunger and pumps no air. Changed it out for another and it helped, but had to duct tape the two pieces together so they didn't separate with each pump. Unfortunately, it made pumping up the ball so difficult that I don't think mine is fully inflated. Would rather have the foot pump that came with a previous model. Doesn't look like there is an easy way to fill it from the air hose at the gas station either. Not entirely happy here...
