I wanted to block the view through our French doors.  I tried gallery glass on the bottom and it dripped to looked funny.  I tried this window film that was easy to cut and easy to apply.  I hope it stays.  I love the prism look it gives!  The only drawback is that the film is so curled because it comes in a roll!  I had to use a blow dryer on really hot setting to help straighten it out.  Without doing that, it was curling after I applied it.  I was hoping to peel off the bottom row and replace it with this window film, but did not have enough to finish it.  Love it though.
