Just wanted a cover to keep debris out of the pool. Purchased pool at Aldi and this fits perfect. It is very lightweight. There are small holes on the top for rain drainage. The only issue is that pool cover would be difficult to put on by self. straps go under pool. I put tubes in the pool so it has some support. Not sure how it would hold up against a windy day. I did have a round pool that you pulled the straps around the pool and on a windy day would come off. Hoping that this stays on.
