At first I received the wrong color tint and it was replaced fairly quickly.  The film is thicker than I thought it would be, so it really is pretty easy to manage.  Be sure to clean the window very well as directed, because every little spec will show thorugh the film.  The only thing that made me score it a 3 was that you can see through the window at night time.  I have only installed the film on the bottom section of these windows to show the difference.
