Review on WALIKI Toys Kids Hopping Ball With Handles - Bouncy Ball For Sit & Bounce Fun - Hippity Hop Ball, Kangaroo Bouncer, Jumping Ball - Pump Included - Red - Ages 3-6 (18"/45CM) by Harwinder Duong

This jumping ball was fun for my 6-year-old for a week; then it ended up resting over the heater vent in his bedroom and got all warped. Waliki also does not describe the sizes of their balls well at all. I ordered a ball for sizes 7-9 and also a ball for sizes 3-6; they were the same exact size. If you by chance end up the appropriate size of ball (and it doesn't accidentally roll onto a heater vent), you child will likely enjoy it.
