I did a search and only found someone selling some on here. I am on a mission to cool my pool this Summer, just installed a Pool Chiller with moderate results. I've been looking into adding a shade sail over the pool and they are wildly expensive as you can imagine. I came across a commercial for Lily Chillers pool floats but I cannot find any real world reviews or honest opinions. They said I'd need 27 of them which comes out to almost $700, not terrible but only if they work. What say you all? I also just saw that they have a 30 day money back guarantee but still skeptical
