I find that the concept is really good. I didn't care to much for the scent as it is very overpowering when you first use it. I hope with time it will just give the car a nice smell.

It doesn't work it doesn't the car small at all waste of money

It really does work and makes my car smell great! I wouldn't say it last over 30 days like the commercial says, but it lasts long enough.

Nice scent that fits well in a work truck and isnt overpowering. small size is easily affixed the the vent louver and stays in place.

Love there always have a spare they are long lasting and smells great

The smell last super long, but I had an issue with one leaking. I'm sure it was just a freak accident.

sent un peu fort mais sent bon

love this but they can be a tad bit strong at first but then goes away rather quickly

These are good but can be very strong. Found them a bit overpowering but the definitely do the job.

I love it, it is one of the best car freshner I've ever tried, it really erases the odours. My car can finally smell great and fresh! But the price is a little bit high, but they smell better than any other ones and they smell longer, so yeah, they're great.
