I have and end of season report as well. I found the rings easier to remove than the regular solar cover. We would just stack them on each other and let them float in the pool . After the swim we would just spread them out again. When removing them from the pool it took a litttle longer than a regular cover but it was easier. So I guess it's a tradeoff.

They do work but not as well as a solar cover. They were great during the hotter months to keep the temp up. However in the cooler months the cover did a much better job of retaining the heat overnight. No surprises there I guess.

I will be getting a solar reel next season to make removing the regular solar cover easier. We will also still use the rings in the hotter months too.
