I have it on my McLaren, I avoid using my wiper blades at all costs and do not drive it that much and still the film has a scuffed/scratched look to it. I am sure it has saved me at least one replacement though so I guess its worth it. My Tacoma windshield is cheap so I am okay replacing that annually.... Unless your replacement costs you $10,000 I wouldn't ever get this crap put on.
