We bought one of these a year ago and my kids loved it. It held up well and they played with it constantly; pretty much all summer. I felt we really got our money's worth with this purchase, so we ordered another one so they would have it to play with it again this summer.
This time it did not turn out so well. As another review has stated, this time one of the sides tilted in a "bow shape" and therefore the house would not stand up well. On top of that, several parts (half of the roof, one of the sides, and the little boat) leaked air right away.
This thing takes FOREVER to inflate, which makes it even more of a disappointment when that task is finally complete and the quality is so severly lacking. I don't know why the first one we bought turned out so much better than the second one, but we won't be trying it a third time. We ended up taking the second one back, and delfating the thing for a return is no small feat either.
In concept it is a great, fun toy, but for some reason the quality factor has gone the wrong direction.
