I also got a warranty for $40. If my window breaks and has to be repaired they put it back on free. Or if I get a police repair order they will take it off for free then I get tested and pass my repair, then they will put them all back on for another $50. I paid a lot for mine, but it's worth it, also with my antenna in the rear window, you have to go with a rubber based tint like 3M so it doesn't affect your radio reception.
