They are okay. They usually only last 15 days max.

The smell is good, but does not last near long enough. I threw it away after less than a month.

I only gave Febreeze Car Vents 2 stars because although I liked the scent you have to turn your heat or air conditioner setting to the vents that blow right in your face. I don't like it blowing in my face so I don't use that setting. Without having the sir blow through them there was no scent.

Scent nice at first, but doesn't last any time at all! I won't buy them again.

It smells good for about a couple minutes. The smell does not last at all to me it's not worth the money. The fragrance does not seem to go all over the car.

I was very excited to receive this to try as I've stood in the store numerous times debating purchasing it. My excitement waned however when I tried it and could barely even smell it. Even with it supposedly on 'high' level, I have to put my nose literally right against it to even get a small whiff (and I have a very, very good sense of smell - it's a family inherited trait). With some people posting the scent was 'over powering' I wonder if there is some internal control issues with the scents? I've had mine in the vehicle for about 5 days now you honestly cannot smell it at all. I love the scent (I use this same scent in wall plug-ins, carpet scent and more) but this car product isn't putting out any scent.

I dont know if I got one that did not work. I have two little ones and have a few things leak in the car so my car has a funny smell. Neither my husband or I could smell anything at all. I really wish this would have worked.

It litteraly smells good for a minute then you can't even tell its there.

At first I thought that I was just getting used to the scent and that is why I could no longer smell it. Not the case. The scent does not last. I have decided to stick with the decorative cardboard I hang around my mirror.

The fragrance is too faint and does not last long at all. I would not waste my money on this product.

I do not like the smell. It smells very strongly but there's a strange scent mixed with it that is very offensive to my nose. It does cover the other odors in the car but it runs out very quickly; only a matter of days.

Not overly impressed it did smell good for about a min. and then it just seems gone unless you put 5 to 6 in your car. Not to mention if you have a van like me with kids who stink up your car with all their things lol.
