I have one of these in my car at all times. And the commercial is right it does last more then 30 days.

They do the job and are amazing little things. I just love anything febreze. Mine lasted for about 40 days.

This product is great because it's not over powering and it smells great. It did a perfect job of masking the odors in our car. Ours lasted about 35 days. Clean linen is my favorite scent.

this is one of my favorites. Way better then anything else I have been putting in my car. It leaves my car smelling great and even after the liquid is gone it still smells great in my car for over a month after. I even smoke and when you get in my car you cant smell a thing but that lovely tropical smell. Love it!

Love these! They really get rid of bad smells, not just covering them up. They seem to work better when the air is on though.

My go to car fresheners. Yes!.....the scent last long after it is empty. Love love love these ....Thumbs up!

These are my favorite car fresheners. The smell lasts a long time and it is not over powering like others i have tried.

I love these!!!! I have dogs and they ride with me everywhere. Thanks to febreze vent clips you wouldn't know it if you didn't see the chew toys.

I tried this product in the middle of summer and it emptied pretty quickly .. I am assuming due to the extreme heat. Not sure if it lasted 30 days but it smelled great and made me enjoy my car a little bit more.

Keep it on my cars all the time ! I love it.

I super love these. They last for about 3 weeks and they have variety of flavor to choose from. Its very easy to clip on to the vent without worrying where to put in for faster way to enhance the smell in your car. I would totally recommend this!

in each car, smells great, everyone asks if my car is new, or how do i keep it so clean! love it

I have never personally used these but my grandma had them and even when it was empty her car still smelled good.
