I find it only works when the vents are on i am able to smell the clip. Otherwise i cant smell anything.

I tried it a couple times but I'm not happy with it. It gives a scent in the beginning for a couple days(very strong and heavy-eewww). and then nothing. It doesn't last for 30 days. In the winter i can smell it if i have my heater on in the car, otherwise no scent. After 2 weeks i don't smell anything at all and there is always stuff left(almost half of it) without giving s scent off. I let it sit in my car for a couple month and this scent fluid is still in there without vaporizing.Not worth my money!

Not worth it. Runs out quite quickly and too strong when the windows are closed. Can give you a headache.

This car vent clip is wonderful. Its cute and compact. However, it does not last me throughout the month. Wish it would last longer! :(

It is a good product but not the best. The smell doesn't last the long. The product does last long enough not 30 days.

I really like this! The smell is not too strong like some others and it seems to last a long time! I will buy it in the future if it goes on sale or I find a coupon!

We like this cause it actually works and its not too strong...use it in all our vehicles and given many away to family and friends...

It has a nice smell, but doesn't last very long.

Easy to use. perfect design...as have known others to be lost down the vent. Great scents

love this. the best part is that you can control the scent. some car fresheners are way too strong and then dont last long with a very perfumy smell.
not this product. the smell is suddle and refreshing and lasts a long time.
got this product for free with a coupon so price was definitly excellent!
