They do work, but rather difficult to remove. There is no advice on how to remove safely, so I do not think I would like to be using them long-term.
A bit scary at first, but after 4 or 5 days of getting used to the tape I wouldn't be without it. I even use it for afternoon naps! I've stocked up 5 packets just in case!
Nice relaxing smell - however doesnt seem to last as well as some other mists you can buy- hence 4 stars
