I do like the cover. It definitely improves heat retention. I can also reassure potential buyers that it is not necessary to completely remove the cover to do daily testing and treatment.
The area I would like to see improved is this...
Something needs to be changed to that water (rain) does not collect on top.of.the cover Ihave solved.the problem (when.the spa pool.is full) by inserting a football between the pool cover and the insulating cover, but when.the pool is empty, water collecting and pooling is a major problem which needs resolving.
