We purchased this in 2006 for our 3 yr old.  She is almost 7 and still bounces in it, but she is close to outgrowing it.  Child # 2 (2 and 1/2) now uses it and has a blast.  He should be able to use it until he is 7 or so.  Well worth the money we spent based on the years of use we will get from it.

Set up is easy, blower has worked fine and canvas has been very durable.
