Review on Freshen Your Ride with Refresh Your Car! 84022 Fresh Strawberry/Cool Lemonade Scented Oil Diffuser, 4 Pack by David Lusk

I found this in a shop about 5 years ago and have not gone to anything else (unless it was sold out). Dueling scents help not to get too used to it. Definitely works better in winter when hot air is blowing on it, I usually close the vent about halfway or more to avoid overloading. And sometimes in the summer I just run heat through the vents to help. But generally every time I get in a car, I get a whiff of him, and other people notice it more than I do. I get so many compliments on it and some people don't even believe I smoke in my car. Very happy with this product.
