I intended to buy larger ball but eventually end up with this one. I have neck problem and smaller ball is better for exercise. I did some exercise following the instructions. It did relieve my neck pain. I should buy a ball earlier.
My baby pushes it around in his walker. It is a lot of fun. Sometimes I put him on top and bounce the ball. Worth buying it.
