Great pool- awesome size for a little one and myself, or to put his Little Tykes slide in to make a tiny water slide! It's easy to set up and easy to drain and clean. The bottom liner is durable and good quality. The sides are flexible, but hold upright very well and are quite sturdy when the pool is full- while filling, although you may have to hold the sides up in some places until the water is about 3 inches deep. I'm really happy with this product and would happily buy a second to replace this one when it finally wears out!
