I put a clip on Refresh air freshener on car vent as per instructions. After a short period of time the liquid leaked out onto my dash and melted the plastic. I did some research and have found this has been happening to quite a few people for quite a while. It will cost of $800 to replace the damaged piece in my dash. I've contacted the company and am waiting on a determination. Facebook has many postings about the damage caused to their vehicles from this product. https://www.facebook.com/pg/RefreshYourCar.Energizer/community/?ref=page_internal
