This ball is the perfect size and inflates to a very usable firmness. It seems well made and durable.

This yoga exercise ball is perfect. It inflates easily. The color is fabulous. It comes with a cloth demonstration poster so you can easily do the workout to get started. I had to keep it away from the dogs as they thought it was for them.

This item is allowing me to do the exercises at home that I am doing in physical therapy. This is going to help me on my journey to recovery. Easy to inflate with a few breaths of air. Good quality item at a reasonable price.

Ball looses air within about two weeks.....

This ball can be semi inflated to allow various types of support in different exercise types

Well, it meets or exceeds expectations. The size is right, the material is good, and it holds air. I'm not sure what it could do to excel, really, but it certainly delivers what it should. It was nice that they include a little tool to pull the plug out of the ball because it's quite tight (that's a good thing) and my fingernails aren't strong enough to pull it out without damage.

Inexpensive,easy to inflate and holds pressure.

This come deflated with a straw for selfinflation. The ball does lose air easily so was disappointed I have continue to inflate. I think I may buy a kids bouncy ball next time for use at a fraction of the cost.
