True the pump that comes with it is flimsy, but it fits nicely into the fabric cover. I noticed several reviews saying that the ball doesn't fill up the cover. I think those folks just didn't read the instructions for blowing up the ball. It takes time for the air in the ball to adjust to the ambient room temp, so it takes a few days to get it completely inflated. It was pretty easy to set up, you just have to wait a few days to get it completely aired up.
