Every kid loves some water fun in the summer or any hot/warm day so we were excited to try this Surf n Slide for our boys! They absolutely loved it! We had an air compressor and carefully blew it up that way and it didn't take very long. If you don't have an air compressor or pump, I don't know how you would blow it up became there is a big hole that air goes into. I wish it was a tad bigger for my bigger boys but they still had a blast on it! For reference, my boys are 11, 8 and 4. My 8 year old is almost as big as my 11 year old. Anyway, they still loved it and played on it for a few hours the first time we blew it up! Water comes out easily at the top of the slide and pools up at the bottom making a nice splash when they slide down. Towards the end, the decided to slide down without the blow up boards that came with it and still loved it. 
Default recommend for young kids wanting some water fun!
