Review on AppleRound 70Cm Space Hopper Ball With Air Pump For Ages 13+ - Hippity Hop, Kangaroo Bouncer, Jumping Ball by Derrick Kadam

First mistake was not getting two. Second mistake was thinking my boys would get sick of it or at least get tired. Two hours later and still bouncing all over the house. It is crazy that something so simple can bring so much fun to two boys of 8 and 10. It comes with its own hand pump. I find that the electric pump is easier if you own one. It did not come with the piece that you use to remove the plug. I had one from an exercise ball that I used. The plugs can be hard to remove by hand. I got the 28" so not only my boys can bounce around, so can I. My boys are 4'6" and 4'8" and over 100 pounds, ya big boys. I am almost 200 pounds and 5'6". The 28" ball works for all of us.
