Loved this window film!  We have a short window that runs alongside our front door.  We don't like the idea that someone can walk up and look down our hallway and see part of our family room.  They can also see up our stairs.  However, we were not comfortable permanently modifying the glass, so we ordered this product.  It works great and does not look cheap.  It was very easy to install.  With the extra amount, we covered the inside of our daughters oval glass front door at her home.  When you pressed your face against her stained glass like door center, you could view inside her home.  We were able to apply this to the inside of her door and you can't even tell there is anything on it from the outside, but it blocks any detailed view of her home.
