These are absolutely fantastic and are a definite gamechanger when it comes to having your car windows down in the Spring and Summer to get some fresh air in the vehicle. Once you install these​​, which is quick and easy, and anyone with common sense and basic knowledge can do it, you no longer have to worry about children sticking body parts outside the window, things being thrown out the window or bugs coming inside the car through the windows. These fit almost all vehicles, with the exception of very few makes and models and are the ideal thing for getting fresh air without any worries of injuries of children, pets, or littering by young ones that know no better. This is a genius product and it's great to see that something like this has finally been made and they will fit most vehicles.
