Review on PONY DANCE Bedroom Blackout Curtains - Light Blocking Solid Soft Rod Pocket Energy Efficient Thermal Insulated Window Drapes for Home Decor, 42 by 45 in, Black, 2 Pieces by Brian Smith

So, first of all, you must understand that you are paying less than $20 for TWO curtain panels. Anyone expecting it to be as dark as a cave will be disappointed. However, I am very happy with this purchase. I bought these because with the time change my 6 year old decided to wake up with the sun. left me with a very cranky first year until lunch. We hung them up last night and this morning I had to wake him up for breakfast and school. A couple of things - I bought them in black which I think would be the most effective color for blocking the light. His window also has blinds, meaning the curtain helps block the light. You don't enter his room and it feels like it's midnight, but it blocks enough light for you to sleep very comfortably in the morning. If you really need curtains that mimic nighttime during the day, then these probably aren't for you. To be honest you probably just need to cover the window with foil for the best possible light blocking.
