It didn't work for me. Its duration was for two to three days. Then the bad smell returned. The worst part, however, was that during application, when I opened the air as the instructions said, the foam popped out and stained my seats, leaving marks that were difficult to remove, only with a special seat cleaner. I should note that I always dry the air conditioning before closing it.

I put it in my Astra j from the air conditioning drain and after the fan, and it did a very good job. The scent lasts quite a while and the air conditioning no longer smells.

I bought a new car and it has a dust smell coming from the air vents. I applied the product for one day and it didn't smell, but on the second and third day, it was the same again. I can't say that it did anything. I don't have anything else to say, maybe there is another cause for the smell, but I will try other products. Mostly, this particular one didn't work for me. Maybe I should try applying it again and not rush to make negative comments, but with the first application on this specific car, it didn't do the job. I will try a second time and come back

Very good product and easy to use. It leaves a scent after cleaning that lasts for a few days. Now, whether it neutralizes viruses and bacteria, I don't know.

Very easy to use, it also has a video on YouTube, it does not leave difficult marks on plastics if the foam spills out, the scent is nice and lasts a long time. One bottle was enough for me to fill all the vents and more. I would buy it again.

I cleaned my car's a/c two months ago and even until today it has a wonderful smell from the product.... I also cleaned the air conditioner of my house and it cleaned quite well too. Super price and worth it.

The positives are its low price, the long-lasting fragrance it leaves, and the quantity that lasts for 2 uses. I cannot know if it does exactly what it promises. In my car, it did not get dirty as I did not let the foam come out of the grilles. However, the tube does not help much compared to tubes included in products from another company that I have used in the past. Maybe I would buy it again because of its price.

Nice scent but when the foam disappeared in 2 air vents, it left a kind of liquid that was difficult for me to clean.

The 4 stars because it has a very nice scent that lasts for a long time, but I didn't see it do a very good job of disinfecting the system because it continued to have a few odors...

If you disregard the incomprehensible instructions and the fact that you have to be both left and right to catch the bubbles and at the same time watch out for the bubbles so they don't go in your eye, it probably does what it says.

Good, it leaves a pleasant smell of cleanliness. Personally, I didn't find the foam form convenient, I had to go up and down the car to wipe off the foam that was flying around during application.
