I bought one of the Hedstrom Hoppers 2 Christmas's ago. The one we bought my daughter was the Tigger one that makes "bouncy" noises as they hop. At first I thought the kids just loved it because of the sounds, but I haven't replaced the batteries in about a year and it's the most used toy in the house. Children who visit go directly for it, my 6 year old loves it and my 8 year old still gets it out at least a few times a week. The children have never used this ball outside so I'm not sure how it does on rough terrain but inside it has lasted all this time never losing air. I agree with the recommendation of 5 years to start since this ball is big but I can't wait to see how long my children keep up with it. My 12 year old son still sneaks in a few bounces anytime he thinks he's not watched, but he's well past the 100 lb weight limit. I highly recommend this toy for someone who wants to give a child a gift that won't be left untouched within a few weeks. Elmos come and go but I still remember the fun I had on my big red bouncy ball from my youth. PS- This is an excellent alternative to a pogo stick for a younger child.
