Solar Pool Disk

[juleswick]

Does anyone have any experience of the black pool disks to keep heat in a pool overnight?

They seem to have been around for a while and are easily available, but I can't find any reviews.

Thanks.

I found a ton of reviews for a different brand on amazon.com, after being amazed they weren't mentioned anywhere in this forum.

They look pretty similar to the solar rings, which most people haven't liked. A quick search for "solar rings" brings up a bunch of commentary.
