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 Daniel Pierce

No instruction manual needed. Five year old boy saw this, hopped on and then continued to hop for hours. He also liked to roll around with it. His cousin had received one an hour before he arrived and the two of them chase-hopped all over the house. I read another review that said take 2 days to blow up, and that was sound advice. We got the pump for free for ordering multiple hoppers. Blew it up first day and then topped it off on day two. We bought 2 of these hoppers but there were 7 total kids. In hindsight, (though it might have been chaos) might have bought a couple of more. The amount of fun gained from this relatively inexpensive toy was priceless. Cannot speak to the longevity of the item, but from the "fun" so far, it was already worth it.
