I have recently bought this as a gift for my husband's new car. The product comes with this "easily removed" sticky pad which allows option for us to easily remove without damaging our car's dashboard or securely fix this product to the dashboard. We just need to pour the oil that is provided with the clay on weekly basis to refresh the scent. This gives us flexibility to adjust the scent strength and our usage quantity. Great idea to have such flexible and mobile products for the car.
