Empower Core Ball and Balance Ring with DVD

The ball measured 65cm as it states on the box, but it just surprised me how small it was. It did not even fit on the balance ring. It may be needed to inflate and deflate it several times, but that could cause stress that I don' think this ball could handle. The fold marks from being in the package caused major discoloring. It was more of a light blue than a royal blue as pictured.The balance ring was okay, but didn't seem helpful when there was so much space between the ball and it. I have another ball I use at work which states that it is 65 cm, but safely inflated to large than that to fit on top of the balance ring appropriately.

Color is blue not the purple shown online, but functions perfectly.
