Product: Refresh Your Car! E300888200 Dual Vent Sticks, Cucumber Melon and Fresh Linen, 4 Per Pack
Overall sentiment: negative
Customer reviews:
doesnt work at all 
 OK, first the good stuff:
It was well packed and arrived promptly ... thanks Amazon!
The form factor is actually quite good. It clips on a vent louver and only shows a small and tasteful button on the end. So it looks a lot better than suspending an evergreen scent card from your rear view mirror.
But the real issue is the SMELL ... especially for an item that is all about the smell.
"New Car Scent"? Really?!!
This thing smells more like a urinal cake.
Honestly, entering the car is like going to the Men's room at Applebee's.
I guess if a raccoon crawled into your car and died then these might be a welcome relief, but jeezz! They smell terrible! Do not buy them.
I removed the one I used after only one day and threw it away. And it took me two days of leaving the windows down and the sunroof open to get rid of the terrible scent. 
 not much scent 
 Does not last very long. 
 basically have no scent 
 Meh - I set all these up in my car at once, and you could BARELY smell them when you first got in the car. I'm not buying again. 
 I had to put 2 at the same time, one in each window of the center of the board of my car and even with that smelled, not recommended 
 I don't get people complaining about the smell, the smell is fine. The problem is that they aren't very good to attach to a car vent, they're too long and prevent the vent from being manipulated, moved sideways etc. Also, the smell only lasts about an hour or two after installation. These really should be less than a dollar for a 4-pack in order to make them worth it. 
 doesn't last long 
 dont last long 
 Cheap product. I feel that this product delivers at the price you pay. Poorly. I recieved a half dozen of these or so an I find that almost half of them are dried up or lack the smell you expect. They also are not great at staying put on the vents. However the product was cheap so I can't be terribly upset as this is what is expected. I would tell anyone to spend a bit more if you want a decent scent stick. 
 Ok, I should have sent this back.  I kid you not, doesn't have a smell whatsoever unless you hold it up to your nose, which defeats the intent of the product.  Don't do it, pick something else. 
 no way to adjust the amount of scent so they are too strong at the start for several days.  Might work by just keeping them in the glove box. 
 These are advertised a "New Car Scent".  Well, I've never owned a car that smelled like this.  Far too perfumey.  I'll pass on these in the future; unfortunately, I bought two packs. 
 I couldn't smell this freshener at all, right out of the package or in the air vent. Maybe it works in a vehicle with a smaller interior space, so I'm not giving it one star. I definitely won't be buying this again.
