GREAT! This is a plug-in that uses pads. It also has a soft green night light. Has very soothing aromatic vapors: Rosemary Oil, Eucalyptus Oil, and Lavendar Oil. These aromas are all ideal for calming, relaxation, & sleeping. Comes w/4refills.
*It should be noted that this particular Vicks product is not for congestion, but rather for soothing and comfort.
