These blackout curtains are true to the description! To my surprise, better than expected and superb quality! After I washed them, I hung them in a room that gets hours of direct sunlight which creates a lot of heat. I hung them with the secondary pull up blinds up and there was no sun shining through whatsoever and immediately noticed the thermal heat from the sun had drastically lowered the temperature in the room! This will most definitely cut the cost of utilities both summer and winter I am certain! Great price for a valuable cutain
