This air freshener is super cute and clips easily onto the car vent, but the scrented oil that comes with it is barely detectable, let alone capable of scenting the whole car. Maybe using another oil would be better but I suspect the whole concept is flawed. You're supposed to soak this tiny circular pad in the fragrance then insert it behind the elephant, and presumably the scent gets disbursed by the air from the vent. However, the pad dries out in mere hours so regardless of the fragrance you use, it requires VERY frequent "refills." In short, buy it for the design but not the fragrance.Its supposed to have a peach smell and it doesn't.
