Fantastic!!
I love, love, love these things.  I am an adult but I still use them. They are no-mess . I use them either stuck to my shirt or to my chest when I'm congested and it gives me better relief than Vicks.  Not sure if they even make them anymore, but I am on the hunt!  They are about the size of a dollar bill folded in half and stick well until pulled off.
