Amazing and great ball for therapy and all other exercise thanks

It's a good ball for Physical Therapy

Works great and just what I wanted

You need your own pump and the process is tricky, measuring space between a wall and a chair and inflating the ball between the 2 objects.The plastic piece for inflation bent while I was trying to inflate the ball. The company that makes the ball very kindly sent me another kit and the ball is helping me with my exercisesThanks for reading!

Worked great after my knee surgery.

Doesn’t come with a pump, but I already had an air. Other then that it good.

I ordered the yellow 45cm Pro-Series ball from ToysNGamesEtc. When it arrived, the package included the deflated ball, an inflation hookup, pins to plug the hole, and a tool to remove the pins. No instructions. No measuring tape. But fine, as long as the ball itself does the job, we could do without the missing items. Fully inflated, it turns out the ball is 30+cm shorter in diameter than it should be--I measured the circumference and divided by Pi, and just in case my math was off I also placed it against a wall, placed a box on the other side, and measured the space in between. It was 111cm. My son is 4'3"--we were worried this would be too big for him since the lower height range is 4'7", but instead his knees are pushed up under his chin. And on top of that, it's NOT a Pro-Series. Comparing what I received to Thera-Band's website, it's their standard ball.RETURN.

Easy to blow up, good color, easy to use.
