Review
This air refreshener is really quite good! I have gotten and try these fresheners from Chemical Guys. Tt wasn't as cheap as any normal air refreshener, and the results it gave was amazing. My car feels really new, the air that circulates in the car cabin feels more fresh as compared to using other air refresheners, and the best part was it actually provides cooler air! Almost like a cooling mist. Totally loving this product.

What I like
The ability to enhance coolness of the air conditioning in your car, and also smells refreshing!

What I do not like
Compared to any other air refresheners, they are quite expensive and not so easy to find.
