Query: Hasn't fallen off my window yet

I really like this product. I cleaned my windows and then applied the shades. They went on easy since it is rolled up on a foam tube, which also helps create static that it needs to cling to the window. I've had in on my car for 2 months now during the summer, which has been in the high 80's and 90's. Other shades i've used have fallen off in just a couple hours in the sun. I also like that I can roll down the windows with the shade still on. Love it!
