Review Content Solar Pool Rings Pool rings work to help heat the pool, retain the heat over night and help prevent evaporation. The ring are easy to remove when you want to use the pool and look festive when in place. The price was right, the ring were well boxed and the freight was most efficient. The exceeded my expectations and I would buy again looks like it will keep pool warmer This looks like it will help with keeping the pool warmer. Great product Convenient storage when not in use very pleased thank you New to me. Seem OK so far. Solar rings placed In pool to warm water. Seem to work OK so far. very useful Great product I have 8 of these guys!!!! With the Texas heat and drought these are essential.... Product is fairly priced, speed of delivery was excellent. In my pool Easy to Use, Easy to Store I saw a negative review for this product on another website and was a bit hesitant to buy it. I can see that these are easy to use, much more attractive and should be more effective than a solid pool cover. Im excited to see just how much warmer my pool will be this summer. We live in NY, so have to have my heater running even into August. Appears to do as advertised An important caveat: For budget reasons, we did not purchase enough of these to cover all of the pool (which is what the manufacturer of these pods advises). Nonetheless, the ones we placed in the pool do seem to have aided in warming the pool by a couple of degrees more each day than solar warming would otherwise accomplish without them.
