Classic Hopping Ball: Ships in Assorted Colors, Ages 3 & up.

Kid tested! What else can I say.
I bought one for each of my small nephews this Christmas, and they loved them. One of the balls came without a plug for the hole, and I don't know how to rectify that except to substitute a plug from a soccer ball or some similar item. Hence the three versus four or five stars. Other than that small problem, the balls are great fun and the kids love them. These have been around for years- and it's easy to see why.

Great toy!
I got this for my 4 year old son who has sensory processing disorder. He is sensory seeking so I'm always looking for good outlets for his jumping and crashing needs. This ball fits the bill and he uses it on a daily basis. It's held up great and I'm sure we'll be buying the next size up when he outgrows this one.

For when your kid is bouncing off the walls
My daughter has used this ball for the last year. It gets lots of bouncing and abuse, but I don't see any signs of it wearing out. She loves it.

Classic Hopping Ball
Kids loved this. Very durable. Adults were using it. Bought it for Christmas in 2007 and still using them (I bought 3- 2 for Kids and 1 for an adult). Good for exercise and kids used the balls for a long time.
