We live in upstate NY. No trees, no shade, so this is on for 5 months all day, every day. Lasted less than 2 full summers.False warranty, this says 5 year warranty. It lasted about 8 months. It was good for 8 months but then started disintegrating in the pool. They would have sent a new one if I paid postage which would have cost more than the product cost. I think honest warranty and product quality would be more important than just making a saleThe product met our expectations. Having been pool owners for more than 30 years this seems to be of greater quality than those purchased in the pastWorks great. Just as described and was a great price.It has two huge holes in it. To return it I would have to take it back out of the pool and try to roll it up small enough to get back in the box.Seems durable, good quality.Good material.... if it didn’t have huge holes it it!
