I compared this product with 2 others sets of curtains from two major department stores. (one starts with "S" the other with a "K") These curtains were mid-range between both stores in terms of price, but the quality is superior! I have 2 large sliding glass doors that face West, so as the winter winds started to blow, I needed a solution. When this product arrived, I immediate loved the color and texture. When I hung them up, they definitely blocked out more light than the other ones I had tried. I can already tell a difference in the reduction of cold air that used to enter my living room. I never know what to think of these ratings when I read them. It's hard to order curtains without seeing them first. After shopping around, I had to leave a comment and highly recommend these.
