It takes forever to fill the slide part. You have to hold the water hose and wait for it to fill the double portion of the slide (they dono't connect together). If you do not put enough water in the slide before you add air the top of the slide sinks in. My daughter loves it, but it's way to big to leave up and it keeps getting holes in it. It took me well over an hour to set it up and the water part of the slide is soo huge that I can't leave it where it is. I ended up grabbing a plastic slide that we had in the yard and putting it in the pool for her to slide down. It is very difficult and time consuming, but my daughter did enjoy all of my work. Wish I had more time and my back could handle leaning over forever.
