Their glass cleaner was really greasy, I cant see out of my windshield even after trying to clean up their mess. To top it off they didnt re-attatch my keyless entrey antenna with 3-M double sided tape, its still dangeling till I can find my roll of tape. I wouldnt let them touch my windows.

Windshield installed, check. But they did a terrible job of cleaning it. They just smeared glass cleaner all over. Probably wont use them again.
