I discovered this ear plug while staying in a suburb on the Windward side of Oahu where dogs barked till 3 in the morning and the roosters started crowing at 5. Suffering from sleep deprivation (I was working full time), I went to the nearest drugstore and bought one of every kind of ear plug. Quiet Down was definitely the winner! As others have said, there is no pressure on the ear that might keep you awake. I have begun using these every night, especially when traveling. Recently have not been able to find these in local drugstores in Cleveland. I hope they'll continue to be available on line!
