I chose this model mainly because of the color and the logo, but also it had good ratings and was the right size. It looked more like a man's exercise ball than many do with the girly colors and logos adorning them.
So far it is holding up well. It was easy to inflate, and seems to be holding the air. After the initial inflation, we pumped it up a little more after giving it time to stretch. Since then we haven't had to put any additional air in it.
It's a pretty bare bones product. My wife's exercise ball came with a really great exercise video, demonstrating a number of complete exercise routines (upper body, lower body, express, etc., each one consisting of various rounds of exercises). This one came with a DVD, but it's more like a flier on DVD than anything else. There's no video workouts on it or anything like that. Nevertheless, I'm not sad about that. I'm happy with my purchase.
