Air Spencer CS-X3 Lime Scent Car Air Freshener Refill - Long Lasting Citrus Fragrance for Vehicles, Home & Office | Eliminates Odors & Freshens Air

I purchased this for a friend that LOVES smell good things; her home has like 20 potpourri bowls. So, since she is a `smell good' pro, I researched the web for quite a while reading reviews from several sites and this product had the overall best reviews.The smell of Squash, in the version I bought her, was a nice citrus smell that most everyone will enjoy. It was almost overwhelmingly strong its first few days. I got into her car again after 2 weeks, then again after 6 weeks and it was still working. I saw a few reviews about it not lasting long... THIS IS NOT TRUE... I can only assume 1 of 2 issues.1) The smell gets lost in smell memory since it does have a powerful fragrance. Like how garbage men or tar roofers no longer smell the odors, the people who purchase the item lose their ability to smell the product. My friend did comment how she could not smell the fragrance anymore after about 2 weeks in her daily use of her car, but I could when I rode with her intermittently. Or 2) they do not put the item in its case. This I assume would cause more air to get to product thus `drying' it out faster than intended.I just ordered this set with case and refills of the other 3 fragrances for myself since it worked so well for her.
