I bought this for my Nissan Sentra and it fits GREAT on the rear window. Very easy to install and it has a few magnets to help keep it in place (unless you have a strong wind, it will stay where you put it.)It has two straps to put inside your rear doors, but it is NOT steal proof. Very easy to pull out the straps on a closed vehicle if someone wanted to steal it.I just used it on my car for the last snowstorm we got (9 inches of snow). While the cover did freeze to the window, it was easy to take off the car without the inner lining sticking to the window.It is lightweight, but not too lightweight.
