It's perfect and does what it says. But as soon as you may down it moves and shift.. yeh..
Other than that it blocks 100% of light. Without fail if placed correctly. Not much fiddling needed. Just push up the nose piece after confirming to nose shape and bam. Darkness.
Just... I feel.. fails once you lay down cause it shifts on your head.
Maybe if.. product main material wrapped further towards ears....
Other than that. It's super soft. Very plush. Not eye hurt. This is great
