Eclipse Nottingham Blackout Grommet Top Single Curtain Panel, Gray, 40 x 95

This is going to sound like a made up review by the manufacturer but its not. These curtains literally paid for themselves in 2 months. I have excellent insulation in my house and my windows do not leak air but I was under the impression that I had solar reflective material on my windows. I also assumed that my other light blocking curtains were solar reflective. They were not. I was literally running my air conditioning 6 hours solid every night without it kicking off in the afternoon and evening. Now, it kicks on 3 times per hour for about 7 minutes during that same time and it runs half as much during the day. I am super impressed with these curtains and have told everyone I know about them. They do exactly what they claim they do. They block the light and block the heat of the afternoon sun. I spent less than $100 to do the 5 windows in the front of my house. I couldn't be happier. I think that this may be the best $100 I have spent on anything in the last 5 years. PS. The curtains look really nice too. :)
