If I could give half
If I could give half stars I would say 4. 5 stars. I ordered 2, one for each side of my Volvo wagon. I was worried about rain getting in the car, but after a windy and rainy night beach camping I was pretty impressed by no water inside the car. The only difficulty so far has been having to exit the car through doors that don’t have the window cover, as once you get it adjusted you aren’t going to want to open the door again because it may loosen it/mess it up. It is easier with 2 people for easier set up (one holding in place while other closing the door).
