Bests & Worsts Reviews from Amazon

Not 100% blackout, but practically blackout. They're way better than the other "blackout" curtains I purchased from Target. Based on some other reviews, I was hesitant to try these. I'm recovering from Post Concussion Syndrome, and light makes my head hurt. I bought these for one room in my house as a test. They blackout enough light that I purchased more for every room of my house except the kitchen and bathroom. The picture is how the room looks in broad daylight (11:45 AM, bright cloudless day, August in California). I think if I was a night shift worker, needing to sleep during daylight, I would probably supplement these curtains with these liners https://www.amazon.com/gp/aw/d/B003CHNBV8/ref=yo_ii_img?ie=UTF8&psc=1 which I put in my bedroom, and they block all light (except the top, which you could probably block with a towel or blanket or something).
