I bought a car from a dealership and loved the fresh scent of the car. After testing couple of other air fresheners, I went back and looked at the pictures that the dealership had posted. I noticed these pads in the air vents. So I used Google lens on it and voila...fresh n clean it is. the scent is really nice and pretty strong though as such I had to put it in the glove box. the first pad has lasted for a month and I think still good for another two months.

I have a new car which I purchased 5 months ago. The leather seats were giving an awesome typical smell until recently when I noticed the smell started to fade out.
I bought these and put one under the back seat and the effect was immediate. People coming into the car again started reacting to the smell and praising it as in the first couple of months I had the car.
the smell lasts for about a month and with the quantity of pads you get in the package you have for months and months of fresh new leather car scent for a decent price.

I tried others in the past which were much less effective and the smell was less close to the real thing.
I definitely recommend these.
EDIT
I came back to add a little disappointment: the package closure isn't as hermetic as it should be and so once you open it to take out the first pad, as hard as you try to lock it back in to keep the smell in for the remaining pads, it apparently flows out a bit and eventually you really sense after a while that the rest of the pads are much less powerful in their scent.
I would strongly suggest you find a way to lock them into a hermetic box so as to keep in the leather aroma as strong as initially.
Still I would buy these again just keep them more properly next time around.
I do hope the manufacturer finds a better closure solution in the future either by individually wrapping each pad or by changing the closure mechanism of the overall package for proper reusability.

When i got my new car, the dealer detail department had them in my car. I kept them in there for a long time. When cleaning my car recently i found one and had to figure out what they were and where to buy them. I called the dealer and they told me the event they use. I found these and they're exactly it! I have one in each door and the car smells so good!

Smells really good, strong scent & lasts for a long time.

I have used these for many years ( Fresh & Clean) and have always purchased directly from Auto Scents however, I thought I would order from Amazon this time, it might have been a few dollars less.
So I did notice with this batch, the scent was not as strong as usual and did not last as long .
I don't think these came directly from Auto Scents. Slightly disappointed but not enough to stop using these and they do have great scents! My future purchases will be directly from Auto Scents for these.
