This bouncy house is awesome.  We've had it set up for two weeks so far, and our kids (5 and 2.5) have used and loved it at least two hours every day. The construction quality seems really high.

A couple parent tips:  
(1) It comes with sprinklers on a hose, but the manual is vague on where to attach them.  They attach to the two square "eyes" directly above the slides, with little ties to route the hose off to the side.  
(2) Water gets inside the main compartment.  You can climb inside the zippered vent in back while the blower is running to dry it out.  There is a zipper pull inside so you can close it behind you and get back out later. :-)  Bring a giant sponge or a bunch of towels, and a bucket.

Part of me feels absurd owning a bouncy house this large, but really it seems like a great investment.  Our kids will love it for years.
