Review on Enhance Your Privacy With BDF BLKT Day & Night Blackout Window Film - 24 Hour Coverage | Size 36X12 Ft by Cory Whitney

I work 3rd shift and used this to block out all the sunlight in my bedroom so I could fall and stay asleep easier in the day.

It works pretty good I recommend it for any 3rd shifter looking for the same purpose.I say it blocked 99% of the light but you can see the sun through the tint but with blinds or a curtain you would never know its there. My room is pitch black when I sleep and that's all that matters.Tested it with all the lights on inside the room at night from the outside, couldn't see inside but could barley see where the lights were in the room but nothing else, no shapes or anything.
