Query: Fun for 15 minutes.

I purchased this for my son, aged six. As the title of my review states, he loved it for about 15 minutes, until he (and I) got tired of propping up the launcher because it's too flimsy to stand on its own. The fins began to fall off the rockets after the second time playing with this toy. Launch height claims are exaggerated unless the person "stomping" is a fully-grown adult - little guys can't generate the force required to send this toy much more than twelve to fifteen feet into the air. Overall, a waste of my time and money.
