This is a well made, heavy duty inflatable slide. Its construction is like that of a whitewater raft. It is easy to inflate with either an electric air pump or a high volume hand pump. My grandchildren, ages 3, 4, 9 and 11 love it. Several adults have also enjoyed sliding on it and it handles the weight.

So why not a 5? After a few weeks of use, the coating is rubbing off of the ends of the "legs" where it touches the concrete decking. This may only be a cosmetic problem, but time will tell. The attached sprinkler needs constant directional readjustment to get it to spray the slide. I don't understand why "boston" valves were used on the ladder and the slide but large push-in type valves were used on the legs. I would have liked "Boston" valves there too as they usually last longer and have less leak problems, but we have had no air leakage. 4 stars
