I used safelight about 8 months ago. The technician didn't know how to remove the rearview mirror and ended up bending the tangs apart, so the mirror flopped around after it was replaced. They also didn't insulate around the windshield very well such that when I go over 40mph I hear a whistling sound inside the cabin. They may be the only ones who can replace the windshield for you, but I would recommend you remove the rearview mirror for them first (you rotate the base using a pin, there are no screws holding it)
