One morning last week as I was going to close my window, I tripped. I stopped my fall with my hand against the window and the glass broke. If the window had not been covered with the Scotchtint film, my hand would have gone through the glass. Because of the film, I wasn't even scratched. Also, the film held the glass intact until it could be repaired the next day. This was an added benefit from the tinting that I had not anticipated and another important reason to be glad that we had it done. Thanks so much for doing such a good job.
