The number one complaint about this product is longevity. That does have truth to it; you lose the initial hit after a very short period of time. But, that's because of two reasons. One, it's a water-based product. It's not designed to last long. Water-based products are gentle and evaporate off, and that's a good thing. Oil-based fragrances can stain and leave residue behind that attracts dirt and dust (and even they don't last forever). Two, your sense of smell works in such a way that it starts to "adapt" to whatever is in your environment after just a few minutes, so that you no longer smell any lingering odors (good or bad) in order to be able to detect new ones. I have given rides to many friends who compliment whatever air freshener is in my car long after I am completely oblivious to it. As far as the actual product itself, this is a great way to try a lot of different Chemical Guys scents before you get a full bottle. These sample bottles are also bigger than I thought they would be. They are the perfect size to stash in a glove box or door panel, and should still give you enough sprays for a few weeks of light duty use. Having used mostly the original "So Fast" apple-scented version, I can tell you that Chemical Guys air fresheners are mostly suited to destroying airborne odors or those that have a very weak source. If you are dealing with things like rotting food, spills, dogs, or heavy smoking, air freshener will only cover the smell temporarily and you're going to have to attack the source. These products are best used as a finishing touch in a cleaning/detailing process, or as something nice to enjoy in relatively well maintained interior (or home). Scent is incredibly subjective, so here is my take: - "New Car" does have that plastic-y, clean smell. Never been a fan of new car scent, but this one is more refreshing and less chemical-y than most, so it's not noxious like those kind of air fresheners normally are to me. - "Leather" is pretty spot on for its namesake. They did a nice job capturing that in a bottle. It probably would make a leather-upholstered car feel a lot cooler. - "Signature Scent" (formerly known as "Stripper Scent," and I'm personally glad they are ditching the frat boy culture) and "Black Frost" are two sides of the same coin. Both are based on women and men body sprays, respectively. The women's is a fresh, vanilla kind of perfume, and the men's is like Irish Spring soap and cologne (or, to put it in the words of a female friend, "it smells like boy," haha). I enjoy both of these. - One review for "Chuy Bubblegum" said that it smelled more like cinnamon than actual bubblegum. For me, I definitely get mostly bubblegum but there is indeed a vague hint of cinnamon to it. I wouldn't be surprised, as it is Mexican-themed in both name and label design. Points for the play on words there, at least. Chuy Bubblegum was surprisingly one of my favorites. - "Honeydew" did not really smell like honeydew at all. It weirdly has a lot of bubblegum top notes with a sweet, candy base note. There is a subtle fruit element to it, but nothing specific. It smells okay; I just don't get any melon off of it. This one was a little bit of a letdown, but I will still use the rest of the bottle. - "Strawberry Margarita" definitely has strawberry to it, but it's more like a strawberry jello shot than a margarita. It is definitely another of those sweet smelling sprays. I was a little unsure if I was going to like this one or not, but it's good. - "Purple Stuff" was the one I was actually most looking forward to, because I love all things artificial grape. I was hoping for either a Crush soda or Jolly Rancher type of scent. It definitely smells like grape, but unfortunately whatever they threw in there to give it the "fizzy soda" vibe to it just smells medicinal to me. It's like grape-flavored chewable tablets. It made me very sad. Overall, I would recommend this to anyone looking to try Chemical Guys scents.
