The Glade PlugIn Scented Oil Warmer will make your home or office smell great. There are many wonderful scents of oil to choose from and they last for around 30 days. I recommend Vanilla Breeze, Hawaiian Breeze, Clean Linen, and Apple Cinnamon scents. Some of the PlugIns come with a built-in nightlight that turns on automatically when it is dark. The Glade Scented Oil Warmer costs about $3.00 and the Scented Oil Refills cost about $3.00 each.  They can be purchased at most drug, grocery, and retail stores.
