GLASS MASTER PRO
This tool definitely makes it easier to wipe the hard to reach areas of a windshield. The concave surface straightens out when you apply enough pressure. Unfortunately, it still takes many cleanings to get all the film off and there were not enough soft bonnets.
I have a auto detail shop, some of the guys' hands are to big to get in corners of windshield by dash. This took care of that problem, and it does a perfect job. No smears!
I drive a school bus and the front is mostly windshield and unless you own a portable crane or cherry picker it's impossible to reach that window for washing. This tool allows me to screw an extension pole into the bottom so I can reach my school bus windshield and the windshield of my Ram diesel truck. The pads do an excellent job of cleaning provided you use a reliable brand of window cleaner.
