I bought this for my kids in lieu of one of those cedar playsets. I figured that I could put it away when they were not using it to preserve its condition. My kids are 2,2, and 6 and absolutely love playing on it. Per the manufacturer, you can get the bounce house wet as long as you let it dry before storing it (not a problem in Texas) and don't get the blower wet (common sense I hope). You can fold it up to the size of a large duffel bag and store it in a shed or storage bench. It comes with ground stakes for safety, but they are not needed unless it is windy or you have large, rough kids.
The reason I gave this product only 4 stars is because the air tube was torn by my son shortly after we bought it. This is entirely his fault, but I feel like the material should have been stronger. He was attempting to move the bounce house by pulling on the tube and it tore right at the strap that connected to the blower. If you can avoid doing that same thing, I think this is a great toy/investment for your kids.
CAVEAT: If you are considering this as a means to make money (like a rental), be forewarned that the material is not as strong as the commercial grade bounce houses, rental use voids the warranty, it has a max capacity of 400lbs (4x 100lb kids), and it's really only big enough for 2-3 smaller kids to play comfortably.
