Installed on 2014 825i S4
Windshield was shipped promptly and arrived on time. The quality of the parts was pretty good. The installation instructions left something to be desired, but a quick call to the manufacturer cleared up the misunderstanding that I had. (He said he would also fix the instructions in future versions as I was the second person that week to call about the specific question I had.)
I've had the windshield installed for several weeks now. The glass is very clear and holds up under all conditions (even towing at 60+ mph).
Overall, I'm very happy.
