We bought these for my teen daughter's room.  The morning sun shines directly into her windows and wakes her up.  We love the color/pattern of the curtain, they seem very well made.  She has grey walls and the colors of the curtains really look nice in the room.  I wouldn't say they are a total blackout curtain, but they do block out about 85% of the morning light.  My daughter is very happy with them.
