I am loving my new stability ball.  I've had it for about a month now, and it is perfect.  It was easy to inflate (although it did take a *little* longer than I wanted; I was so anxious to try it out!), and has served me well.  This is definitely worth the money if you're looking into buying a good stability ball.
