I have had 4 small kids playing in this at one time, with no problem. It has only been used several times, but seems very durable. It blows up in less than a minute, and I have had no problem rolling it back up to fit in the travel bag.The only con, every time I inflate it for my daughter, all the kids in the neighborhood come running over to play in it also. Hard to miss, it's huge and bright.Overall, a great toy for the money, and I would buy it again.
