I have the clover patch window roll. Used it for the first time yesterday. It is really easy to use. I didn't like having it on the back, though. It blocks a decent amount of view. It does fit in the trunk though. I am going to try and buckle it to the back headrests or something. Or maybe on the back roll bar? It is pretty nice not having to worry about where to put your windows and them getting scratched and whatnot, though.
