Review: Picked up the 1200 series in March of 2023. It's been on the pool summer 2023 - summer 2025. It does exactly what it's supposed to - maintains and keeps heat in the colder evenings, prevents evaporation in the warm ones. In Northeast Ohio - so this is a short-use season (May through Sept); Just started to notice the blue bubble failure and had my first edge tear during closing. 3 summers is what I anticipated to get out of this. It is not a permanent solution - you will need to buy another. We picked up a cover for it, and I think that made a difference. the prior homeowner left his in the sun and complained they only lasted one season. Note - The 1200 is heavy for a 20x40 pool - buy an appropriate reel. the 1600 is likely overwhelming. I will buy another in the winter of 2026 - this is a no-brainer for us.
Review: As one who has used pool covers for the past ten years, I can attest that this is an excellent product. I know that your thinking "how is one pool cover better than another?" Two main reasons: One is that the seams are well sealed. I've had covers where the seams started to become unsealed within a few weeks. Second, it is a precise rectangle. That may seem unimportant but for someone who has rolled up a pool cover at least a thousand times, I can tell you from experience that covers that are off by even a couple inches makes the process of rolling up the cover rather tedious and time consuming. This one I can roll up in maybe 60-75 seconds. Rolling up a pool cover is a pain in the first place but if you know you can do it quickly and efficiently then it makes that spur of the moment midnight dip in the pool that much more likely! For those of you on the fence concerning a pool cover, let me tell you the benefits I've noticed. 1. You can heat your pool easier. The numbers I see thrown around of up to ten degrees are for the most part true. Before I started using pool covers, I could hope for a summer time high water temperature of 80-82 degrees. With the pool cover I can keep it at about 85 with ease (too warm for my taste but that's how my wife likes it. I was gone last weekend and when I took the cover off on Monday, the water temp was 90 degrees! I had to keep the cover off for a couple days to get it back to a suitable temperature. 2. It saves on chemicals. Now of course, the higher your water temperature the more chlorine you go through, but with the cover on it keeps the chlorine from leaking away into the atmosphere allowing it to work in your pool longer. 3. It saves on water. The way you heat water is by evaporating it, but with a cover, that evaporating water goes right back into the system. During the summer I can lose maybe a quarter inch of water a day without the pool cover on versus a quarter inch every couple days with it on. In fact the only time that I'm losing water is when I take the cover off to swim. 4. It keeps the pool cleaner. I honestly haven't used the automatic vacuum in nearly a month. I pick up the few leaves that get in by net but I haven't had to clean it in any other way. That in itself is a real time saver. All told, it is a bit of an outlay for the entire reel system and the covers last only about perhaps 18 months at best, but overall I would consider the pool cover system to be one of the better purchases I've made. And as for the pool cover, this one has been an excellent purchase and value. I will surely, 100% buy my next cover from them.

Sun/Solar outstanding company located in Ca. I only gave 4 stars because I just put it on and we’ll see how long it lasts. 1200 series is the standard middle grade. And for the price it’s a good deal. I called the co. Directly before ordering and rep answered all my questions and gave me peace of mind to go ahead with order. I’m not dissatisfied about the quality or thickness. Came on time from co. Wrapped in a heavy duty plastic bag that will be good for storage. Can’t beat the price at your local swim pool place. We’ll see if it makes it thru two seasons I’d be happy.
