Review on Ceeniu Car Air Freshener - Solar Energy Rotating Perfume for Long-Lasting Fragrance - Luxury Car Air Diffuser with 3 Aromatherapy Rings, Cologne & Marine Scents - Perfect Gift Choice by Kevin Garcia

I've never had a solar powered air freshener so this was very new to me, I'm very happy with it but it works well. In direct sunlight, it turns itself on and distributes the fragrance throughout the car. The aroma is strong and fragrant, but not overpowering. Not sure how long the scent lasts but they give you 3 replacements. It attaches to your car with a small adhesive pad that you can stick and re-stick as you like. I only have 2 cons with this unit, the solar part doesn't work well with dark tinted windows and the cost could be lower I think. However, it works as intended and smells nice in your car.
