Love this shade! It is definitely 100% Blackout-type of shades. It keeps a lot of light and heat from the hot sun out. I keep this in my sunroom and it definitely has made a difference keeping the room cooler. I have it down during the hot sun hours and roll it up when it is not so sunny. The mechanism to roll this shade is smooth and works great. The color and design is sophisticated. The material feels durable but easy to clean. This is definitely a keeper!
