Midwest Canvas 18' Round Swimming Pool Space Age Solar Cover with 6-Pack of Grommets

I need to have a solar pool cover on throughout the year just to keep the water from evaporating and to get the water warm enough. I don't use the heater due to the cost and I was surprised at how well this solar cover heats the water. This is the first year we've had the water temp up to 89, so I've learned to take the cover off earlier in the day so it doesn't get that hot. This cover works better than all the other covers in the past and assume it's the diamond shapes or because it clear plastic. Not sure. It's also not as heavy as the other ones I've had in the past so it's easier to take off. I rated it a 4 because I don't know how long it will last compared to others I've purchased. Time will tell.

We purchased this pool cover in Febuary 2018, by September 2018 all the diamond bubbles were falling off. We had hundreds and hundreds of plastic diamond bubbles floating in our pool and clogging the filters. This cover is JUNK, what a waste of money! A pool cover should last longer than 7 months. Do not buy a pool cover from save-more-on-pool-supplies. Customer service was NO help with refunding our money. They claim the warranty does not cover this.
