Looking for something that really smells good? Get an Air Spencer CS-X3 (Squash). Directly imported from JAPAN. They are very slim, clean, and are refillable. You can’t get these at your local autoparts or retail stores. You can either purchase them on EBAY or find your nearest local Japanese shop. Also, if your really lucky one of those Japanese asian markets might carry them. They are around $12 and really smells good. Since they are imported that means that this unique scent can’t be found in the U.S. but in JAPAN.

How Long does it last?
It can roughly last up to a month, but this totally depends on the weather conditions. If it is really cool it will last longer, but if it is really hot like summer it will probably die out in less than 3 weeks or sooner. The heat in your car will determine how long it will last. Thats why I recommend parking in the shade or leave you windows down a bit so your cars interior can cool down during hot summer months. Best, avoid direct sunlight.
Update: Driving with your windows down also will reduce its lifespan to 2 weeks. Info was provided by Kendall.
