I bought these blinds for my sunroom windows last year and loved them. The room needed a pick me up and these did the trick. Installation was very easy and they look as good as custom blinds. They are not light blocking but do filter out the strong afternoon sun. I got so many compliments on the blinds that I decided to replace all of my wood blinds with the bamboo blinds. I was so happy to see that they were available again this season.
