Solar Powered Car Ventilator Window Solar Exhaust Radiator Fan, Window Windshield Auto Air Vent Cooling Fan System Cooler

This product is cheaply made, broke on the first use. Does not really do anything, car still feels really hot after use. Mechanically it was ok. This product is sun powered which is pretty cool and useful, however the fan blows slow and like previously mentioned it does not really do as advertised.

I've had these exact units before and they work well enough to keep the inside temperature equal with the outside so you are able to enter as well as touch the steering wheel. I did see the triple fan model, but figure the fans might be smaller, so I went with my experience. I bought two, for when I'm not sure which direction the sun will be. May not work if you park in heavy shade so please do not take a chance leaving your dog in the car.Take care raising the window as the units aren't completely unbreakable. (In which case there's always duck tape)I've been very happy with this purchase!

Does not take a lot of heat out needs to have at least four reduce temperature in a car

Bought this in the hopes that it would bring cool air into my truck. After installing the fan the movement of air was nonexistent. My truck did not cool down in any way. If the sun isn't shining on the device then it doesn't work. So when the sun moved throughout the day it stopped working. This was not worth the money.

It doesn’t work if you have tint and the fan isn’t strong enough for anything I don’t feel any of the air coming out so basically it has almost barely to zero air flow. But I can feel it going in but not going out so do what you will with this review.

Moves the air fairly well. It is chunky, the inside head rail on my truck makes the gap in the window fairly large. A slimmer, but wider over the top of the window would have worked better on my truck.

Was skeptical because of all the other reviews, but wanted to try it anyways.100% not worth it. Do not buy it.Leaves a gap in the window, even with the extra weather stripping. Does not cool down the car at all. I feel like you would need 1 for each window to even make a dent in the coolness.It broke after a week.

I have been using these for several years and they work by pulling out the upper level of heat in a vehicle that accumulates at the roof . You must park with the fan vent facing the noon to later evening sun so that the solar cell will activate the fan to exhaust the heat. Here in Texas it has been over 100* every day and this little exhaust fan really make a difference when you get into your vehicle. You simply roll the window down a couple of inches and hang the vent fan over the top edge of the window and then roll the window all the way up. When the sunshine hits the vent solar panel it starts spinning the fan. Use windshield shades to assist from blocking a lot of the direct sunshine into the vehicle.
