Review on AppleRound Space Hopper Ball With Air Pump: 28In/70Cm Diameter For Ages 13+ - Hop Ball, Kangaroo Bouncer, Hoppity Hop, Jumping Ball, Sit And Bounce by Maurice Morris

I grew up bouncing on hoppity horses, and then bought my kids hoppy balls when they were little. Such a fun activity to bring cheer and laughter to the home. So, when I saw hoppy balls for adults, I couldn't get it in my cart quick enough! ha!I got the 28" (diameter) ball that holds up to 300 pounds - hopefully it really does and it doesn't pop on us! It's definitely a thinner rubber than what I grew up with - more like an exercise ball (although, not even that thick). My kids and I hopped around for hours the day we got it. My 220 pound husband even bounced for a bit (although he's 6' 2" so he's probably a bit tall for it to be too much fun.)The air pump is handy, although slow going. We measured the circumference to make sure we had enough air in it. Since it's 28" diameter, that makes the measurement around the ball around 88".We're having a blast with it!
