Lots of fun for the little ones.  Blows up in less than a minute and our daughter is a bit hig with her friends.  She can't get enough bouncing.  I wish that it didn't have an access "window" on one side as the little kids could fall out (better to only have the slide access which is what all the kids use to get inside anyway).  However, overall, for the price, ease and quality (not commercial quality material but $800-$2000 less than commercial) we consider this a big win and good value. Depending on whether you want balls, you may wish to get three packages as one package of balls is not quite enough.
