Query: Large but difficult to use

This pool is very large--which is great if you have a huge, completely level space in your yard in which to set it up. (We don't.) Set-up/take-down is difficult due to its size and the "floppy" nature of the sides. It takes a lot of water to fill. That said, our son had fun in it the one time we tried to set it up. We ended up giving it away and purchased a smaller pool of molded plastic.
