Tired of the closed up winter drives to and from work? Me, too. My car smells fresh after I just clean it but the odor becomes stale and the air can be just 'car' smell. I got this lovely little car diffuser for essential oils. It just plugs into the cigarette lighter with a USB adapter or if you already have a permanent USB plug, then you're all set. The unit uses a small amount of water and a few drops of your favorite essential oil (lavendar). I just plugged it in and immediately I had the wonderful fresh smelling vapor rolling through my car. I love the colored light feature, too. Very easy to clean and the instructions are very self-explanatory.
I received this product at a discount in exchange for my honest and unbiased review.
