Some people might work great...me not so
does great blocking LED light form electronic in the room, after you get accustomed to the darkness you will be able to see a small amount of light. I used to live in a basement that had pitch black darkness so it does take a LOT to win me over in this aspect. the mask is very soft decent build quality, i will continue using this till my blackout curtains arrive. but great price for what you get.
