Our granddaughter, 3 yrs old, loves this water play center.  We do need to put more air in the slide and step part next time to make it a better sliding and step event.  She pretended to take a shower, get caught in a water fall, through food at the croc, and floated in the water.  Def need a compressor (thankfully hubby is a mechanic and has one).  Also like that you can adjust the pressure in the water features.
