I bought a Stomp Rocket to take to a week long family reunion which involved kids of widely varying ages - they absolutely loved it and played well together every single day for the whole week with it - really great ( often hilarious ) fun and it had them all running around tiring them out for bedtime - my three year old played with his cousins aged from 6 to 9 and even the adults wanted to have a go. I cannot recommend this highly enough and have just ordered two more as presents. Be sure you have an open space though as we got the rockets stuck in trees a few times. Physical fun with educational element too as the kids learnt different directions and made up different modes of stomping (eg backwards, side to middle, recommend the sitting stomp ! ) I love this.
