Bests & Worsts Reviews from Amazon

What can I say, it fulfils its purpose perfectly. My bedroom only has mini-blinds, and since I'm retired, I'm through with getting up with the first sunlight. I got this with the idea that I might be able to sleep until my dog needs to be fed. To be frank, I did not hold out any real hope for it. I expected it to be uncomfortable and inadequate at keeping out the light. I was wrong on all counts. Now I sleep with it every night, and apart from being able to sleep until the alarm goes off, I don't notice it at all. I am a convert, and recommend it for anyone who actually wants to be kept in the dark.
