Very easy to use but also a quality product. The reason for the 4 stars is because, compared to some slightly cheaper products, the difference before and after is not so striking as to justify this difference in price.

It indeed removes odors, but the scent that claims to last up to 4 weeks does not hold true. It lasted about 2 weeks for me. However, when you turn on the air conditioning, the cabin filter has absorbed it, and it smells again. If it were slightly cheaper, it would be worth it in my opinion

I tried this specific product, and then the equivalent from wurth. The meguiars is 15 levels above. The scent lasts much longer than a common air freshener
