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 Kimoni Arenas

Unbelievable how well this works. The scented rings last a very long time, I don't feel any difference, and when I first opened one, after a week +. And there is no problem with us running away from sunlight, even in low light and cloudy conditions it seems to work very well. As you can see, the design is attractive in that it doesn't interfere with vision and doesn't stand out when driving. My plan is with the rings after they run out of sand as they are porcelain you can just add any scented oil to them and change the smell. Very happy with my purchase. I hope that was helpful.
