We started using them after they bought out the company that installed our pool. We were away last Friday when they came to close our pool. We came back to the cover half in the water (see picture). Some of the grommets did not work. They did not contact us to ask if we wanted them to repair them when they were here last Friday. They came back today after a number of phone calls, and the issue was fixed. We were promised they would come back in a couple weeks to finish replacing the grommets that are still not working. The gentleman also promised he would speak to the owner to make sure the issue would be discussed with the employee who was here and left our pool like this without contacting us first. I was going to give them a 1/10 before they showed up today, I am now more satisfied and this is reflected in my rating. You just need to make sure you are there when they come to avoid a similar situation I guess.
