We are very pleased with this purchase.  I bought it early and saved it for a Christmas present, the kids are over the moon excited.  We have bought several Little Tykes jumpers over the years and they have never lasted more than a season.  This plus the fact that our boys are getting older and bigger lead us to this purchase.  I will update the review as to the longevity once we have had it longer, but so far it seems very durable.  
It is huge, definitely has room for several kids, and accommodates larger children (my oldest is 8) well.  The blower is quieter than one normally of this size, so that was a nice surprise. Plus no more jumper rentals, this is definitely an industrial bounce house!
