Title: Extremely disappointed - How can I return
Review: Was supposed to be a 45 cm ball. I don't see how. Even when I inflate it to as much as it seems to hold, it still does not measure 45 cm. But, even if it is (and I am doing something wrong), it is certainly not functional. The ball is hard as a rock. So, given it's size, makes it impossible to lay on unless you want to feel like you are pressing your abdomen against a rock. Worthless.
