I purchased this SudaCare Nighttime Vapor-Plug. It is made by the same people that make Sudafed nasal decongestant. It is pretty cool. It is a mini waterless vaporizer. It works like Vicks rub, except you plug it in. I know my seven year old daughter cannot stand to have Vick's rubbed on her when she is sick, even though it would help. You put a little pad in this machine and then plug it in. It releases the menthol and eucalyptus vapors while you sleep.
The pads last up tp eight hours, and are easy to replace. It takes up to an hour and a half for the vapors to completely fill the room. It would be best to have the unit as close to the user as possible. I really like it, especially for a sick child. This product will allow then to sleep better. One downfall is that you have to remember to unplug it in the morning. It is not supposed to be plugged in for more than 16 hours. Other than that, I like the product. It is soothing and easy to use. One other down side the refills can be hard to find.
