Title: Does the job
Review: I like this exercise ball just fine. It's apparently well made and very sturdy. I wasn't missing any parts -- in fact, I wonder if I ended up with someone else's missing plug since there was an extra one in my box! Actually I hope that means they are packing them with a replacement plug now in case the original is lost.Regarding the size, I'm barely 5'6" and my legs are a little on the short side, so it is slightly too large for me fully inflated. But since I wanted it for sitting at my desk as well as exercise, I took the chance with the 65cm ball. The instructions say it doesn't have to be fully inflated, so I just let a little bit of the air out and it works great for both purposes. So far it is holding the air without leakage. I would buy another one if I ever need it.
