Review (5/5): Turns day into night.
I've used this for the past few nights and it only came off on nights were I slept more than seven hours. It is very, very comfortable and even though mine does not have the nose flap, it does block out all light. I am extremely happy with the product. I use masks for dry eye syndrome, not insomnia so I use them every night.
The price is $18 on Amazon, which is a great price for a comfortable mask that is large enough to block out any light.
