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.

Great smelling and leaves my car smelling great all the time and easy to use

Amazing product that gives your car a fresh clean scent for weeks to come !!!

Surprisingly doesn't just mask the small. Love the great scents!

this freshener works great I even sometimes use it in my house when I run out of air fresheners put it on a vent and turn on the AC in the house or in the car and it works perfectly

We loved the vent clip! The scent was not over powering and did a wonderful job of hiding old car odors.

I keep these in my car at all times! Even once the clip is empty, I still smell the scent clip for up to a week. I highly recommend these.

I love the car clips. At first I was worried about the scent being too strong. I am sensitive to strong perfumes, but to my suprise it has a nice fragrent. The fact that you can adjust the level of intensity is perfect. My car smells fresh all the time now.

I LOVE this product and I recommend it to everyone! Anytime I have a friend or family member in my vehicle, I am always complimented on the smell of my vehicle! I take a great deal of time to be clean and smelling good in both my home and vehicle, febreeze vent clips help me attain maximum fresh smell on the go!

There is no other car clip that works as good as these! I was amazed when I first used these. My car smelled new! I loved these so much that I had Santa put them in my adult kid's stockings!
