"I bought this for my son for a Dinosaur party. From the first time we blew it up, it had a slow leak. Within a half hour, it would not stand up anymore. We made the best of it and kept blowing it up until the party so that the kids could play with it. In the end, they loved jumping on it and wrestling with it and it helped make the party a hit, however, I was disappointed that it leaked from right out of the box. If you are lucky enough to get one without a leak, then it makes a great party prop."
