Love the Pump  Splash Pond! Big enough that my 3 year old can sit in it and easy enough for him to play with it without assistance. He can play with it for hours. It was even fun enough that my 32 year old husband was possibly having even more fun with it. It was a little difficult to put together because I had to make my own holes to screw the screws in but easy enough to do without a drill. Would highly recommend this play structure!
