Very strong smell at first to the point that you can't be in the car with the window closed and in 3 to 4 days it disappears completely, maybe necessarily because you can't close the window! Fortunately, I did it in the summer, and I didn't like this particular scent either.

It really does an amazing job, which in my case lasts for a few months (3-4), but I believe that depending on the severity of the odor in the car's air conditioning, it may last even longer. However, it is useful to remember that it does not in any way replace professional care of the car's air conditioning (e.g. filter replacement).

Easy to use, eliminated the unpleasant odor from the a/c, and more than a month later it hasn't returned.

For its price it's ok, after a week its scent disappeared but it also eliminated the strong odors from the air conditioner

Excellent product for cleaning the air conditioning system and renewing the air in the car cabin. Nice, discreet, somewhat "masculine" scent, eliminated any odors that existed and kept the air cool and fresh. It did not leave the slightest stain and was very easy to use if you follow the instructions.

For the past ten days since I used it, that musty smell that used to appear when I turned off the air conditioning and only the fan was running has disappeared. There is a very subtle fragrance left that it gives to the cabin.
23/9/24: The fragrance is gone now but so is the annoying musty smell. All good!
5/6/25: It lasted just fine for 10 months. As soon as the bad smell barely appeared again, I used another cheaper one, which lasted 5 days. I will buy this one again immediately.

The scent is nice. But within a week with the car not moving, there was no smell left at all..
