Definitely help your vehicle to smelling fresh!! sometimes you have to have the heat or air on but if you add a bunch of them to your vents then you will smell them right when you open your door. they do the job!

I love their scent and I think they really help to remove odor instead of just covering it up. With three kids I don't even want to talk about the smells that can happen in a car. We have used these for months and the car is always fresh smelling, the cartridges also last a pretty long.

Love the way my car smells when i use these! The fruity smells are my favorite

I love love love this product! They cover up the smell of stale cigarettes! People who ride in my car rave about the amazing smell,

I always have one of these in my car, It makes the car smell as if I had just had it cleaned. It takes out any lingering food or smoke smells. I always keep a spare one in the glove box for when one wears out. Theu last a long time though and it's much nicer than having pine trees hanging from my rearview mirror.

Kinda strong at first, but is an amazing smell. It lasts a long time too

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

All the smells I have tried are very nice and not obnoxious. Love how I can dial up or down on the amount of scent. Thesseem to last a little over a month for me. I especially love the Gain scent. It is neat how you clip on vent so the smell blows out.

I always get these because you can get the big pack of them for really cheap at Sams Club! They last forever thats for sure but the only problem with that is they are VERY strong! We like to put them under our seats instead of in the vents so it still makes the car smell good but it is not all in your face!

Love these, they keep my car smelling fresh no matter what the kids leave in it!

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.

LOVE these! They smell great, are not too pricey and you can always find coupons for them! The only thing is, they definitely do not last 30 days.

I love these !!!!! Having five daughters that plays sports my car gets a funky smell I keep the febreeze vent clips in my car and bam funky smell gone.

Great airfresherner for your vehicle. Place in the vent and the air that circulates is really nice. Large selection of scents. Inexpensive.

We use these in both of our family vehicles. We love every scent we have tried!
