Liquid solar covers??

I saw the little floating fish solar cover at the store the other day. Does anyone know how these work or if they are good for our pools and water chemistry? Not sure what the liquid would be? Anyone use them with success?

I asked the same question, sounds like it's just a gimmick.

Thanks, I can't believe how much crap these pool companys try to sell us!
