Review on 🌞 BDF NA20 Window Film Privacy and Sun Control N20, Black (Dark) - Enhance Privacy and Block Sunlight with 24in X 14ft Film by Valerie Jones

I closed the sliding glass door, two large bay windows and a smaller window in the bedroom (with more tent stock). Installation was very simple and easy. Take your time, measure twice, cut once. Make sure you wash the window fully before applying. I also took a metal scraper and lightly went over the entire surface of my window. You will be surprised by small dust particles and particles that you may not see but that can create textures and bubbles on the film. My foil and packaging arrived intact and rolled tightly. As with any tinting film you need to be careful as it creases easily but this is not film proof it is application proof. If you are patient and careful, you can actually avoid wrinkles, bubbles and stains. If you are inexperienced or new to applying tints, I would definitely recommend watching a few videos on the best installation methods. I would also suggest having all your materials handy and working in a wide open area. Of course, the larger the piece of film you're working with, the more likely it is that the film will stick to itself, pull dust into the room, etc. I didn't give a 1 for a few very minor reasons. First, when you unpack the screen, the little plastic end cap holders in the box were not attached to the box and slid a bit when I unpacked them (like pulling paper towels out of a roll). I would like to attach these end caps to the box to make it easier to set up the umbrella. Second, although the tint was a lot darker than the original regular glass, I wish it was a little darker. Maybe it's my fault for not buying a darker shade, but based on the photos, expectations were a bit off. However, tinting definitely reduces heat transfer. I'm in Arizona and even 10 degrees makes a difference. With an infrared thermometer it was 10-14° colder than with untinted glass. All in all, I will definitely buy this product again!
