Query: A disappointment

This product was too small for our 4 year old sister. The child on the front of the box looks like he's 9 and it says for children 5 and up, but she could barely bounce on it, it was so small. She's used it, maybe, 3 times and it's now deflated because it won't hold air either. Wouldn't recommend
