This is been the best purchase we've made in a long time. Every time the boys are getting rambunctious we immediately send them upstairs to the bounce castle to jump out all of their energy. It's work perfectly inside our home during the colder winter months but we look forward to also using it outdoors as well when the summer comes. Amazed at the commercial grade quality. I think this thing will last a long time even with the abuse my kids are getting it. Two thumbs up!
