Review on WONTEX Blackout Curtains: Thermal Insulated Room Darkening Grommet Drapes For Bedroom, 52X84In, Taupe (2 Panels) by Brandon Battaglia

They do block out close to 90% or so of sunlight. I needed some light beige blackout curtains. I ordered by mistake the grey curtains and was very pleased with how much sunlight and heat it blocked. So much so that I decided to keep them and used them in a different room. I then reordered the light beige curtains, being careful to make sure I ordered correctly this time. The light beige does not block as much light as the darker grey color. A little disappointing. Buyers should be aware the darker colors seem to block more light than the lighter colors. Also after hanging about 24 hrs, all wrinkles are gone. Material looks great. Overall I would give them 4 1/2 stars, subtracting a half star for the lighter colored beige not blocking as much light as the darker grey color.
