It works very well because we live tucson arizona and it gets very hot the fan cools the vehicle with solar panel and it does it really pulls out the air!

I purchased Auto Cool and it's really Work! The airflow is being work and the unit work with the solar panel directly facing the sun.

Yes it is lightweight......that can be a good thing. Now you can feel the breeze and they do cool the car by about 2 or 3 degrees so the steering wheel is not hot. The seat is hot and the car can be gotten into with Cool . It's for moving the air so that your car can be gotten into Cool.

The fan works great. I try and park the sun is shining on it directly and it's work great. Without Fan the interior of my vehicle to get to 150 F or higher. Now with the Fan it's within a few degreees of ambient temperature
