Bests & Worsts Reviews from Amazon

We needed this film to improve privacy at night (due to gaps in the window shades); and to allow for natural light in the daytime without worrying about anyone looking in. This film does a great job of preventing anything from being seen from the outside or inside. We tried to peer in the window from the outside in the dark (with the interior lights on) and during day time. You can't see anything. that being said, I left the top 1/4th of the window free of the film, so if something is going on outside the blinds can be raised and we can look out. If you have a little gap between the window and the blinds the top 1/4 edges can be filmed with a little strip on either side to prevent anyone on the outside from climbing up on a chair or something and peeking in. Otherwise if you film the whole window you will need to open it to look out, because you can't see anything with this stuff. It was very easy to apply. I just cleaned the windows very well and used a T-Square and a cutting mat to get things neat. I used an empty spray bottle to mist the windows with plain water. I trimmed excess with a straight edge and a razor blade. I used a rubber spatula head (taken off the wooden handle) to smooth air bubbles out. I could have been neater with that, but it's fine for me. I love that when we are done with this it can be easily removed. So far it's been on for about 2 weeks with no issues.
