[This review was collected as part of a promotion.] These Febreze Car Fresheners really work great in our car. They are easy to activate and to attach to the car vent with the clip. I love that you can adjust the intensity of the scent with the dial. The Hawaiian Aloha scent is so refreshing. It helps to refresh the car and to eliminate stale odors from food or stale vent air and any other unpleasant odors. This is a great way to keep the car smelling fresh and clean. Highly recommend!
