    I absolutely love our Prism ball. We have the green one. I know that we should have the right size for our height but we use it for multiple reasons. We homeschool and wanted a ball that could be used at the table so the kids and I could have more movement while working. We also use it for different exercises. The kids like making up new ones but I love that there are movements printed right on the ball. This ball comes ready to inflate with its own pump and tape measure. Great activity for the kids. Also, I liked the help with knowing how much air to properly inflate the ball with. This ball also comes with extra plugs and a tool to remove them. Very well thought out. Thanks Prism.
