I purchased 5 Custom panels, pre-cut to fit 5 sliding glass doors. I found them very easy to install by myself. They have totally changed the look of my glass doors into a beautiful art design. No one thinks they are not real windows that were custom made for the house. Barbara was so helpful with my order and the delivery of it. The quality of the film is so nice to work with. I would highly recommend it. Plus it is made in America!
