Worked since using it.
At first when i received it i thought how it help me fall asleep faster but after using it for 3 nights i found that i slept in minutes and did not get bothered by lights/noise of any sorts.  The only strange thing i find is that after 6 or 7 hours of solid sleep i would guess the head movement the piece comes off.  The only other thing is what happens in the summer when it is warm but i am willing to take that chance.  I really found that the wrap-a-nap works and would recommend it to anyone who wishes to try it.
