I started using it back in the 80's. I use it all the time on all my vehicles. The big trick is to make sure that your glass is very clean and rub it on until the tiny drops don't form any more, let it completely dry for about 10 minutes, then buff the hell out of it with a cotton towel. when you are buffing and see streaks, you haven't buffed enough. I don't have a problem with glare at night just with little rain (mist) and low speed and the water not running off but when that happens the wiper take care of it.
