I`m not a fan of it on the windshield, I installed it about 2 weeks ago and both times I have been driving at night in the rain there is a haze on it when wipers are off when you go under lights it takes away your visibility. With the wipers on its not as bad but there is still a bad haze to where its hard to see out of. So I`m going to compound the window out when I get a chance.
