I haven’t decided on where I want this to go yet but I’d try it out back in the summer in a paddling pool and it was pretty good. Just remember to put it in something that will re-catch all of the water. To begin with I didn’t do this and the water ran out quite quickly (my fault). With the right setting and surround it does exactly what it says, just remember to pick a nice sunny spot and check the water lever every day - especially in the height of summer!
