Review on 🖤 Opaque Matte Blackout Privacy Window Vinyl Film - VViViD Decorative Decal for Home, Office, Bathroom, Kitchen - DIY Easy Installation, Adhesive No Mess (17.75" x 60") by Kelley Zulkifli

It was very difficult to install but in the 2nd section I somehow figured it out. The backing is done pretty well and I thought it had no backing until my cut caught and managed to peel off. Bought 17.1x60. That was barely enough to make two sections of a four panel window. When installing, be sure to install in daylight and trim slightly on the outside where the window connects to the frame. I found that after drying the film had shrunk and white light was coming through the edges. It's designed to be washed so no one sees it, but if you're installing it in a higher traffic area, be aware that it may shrink a bit. There are no instructions included and the instructions on the Revain purchase page are very fuzzy. It would be helpful if these troubleshooting points were noted by the seller. I gave it an extra star because it dims all incoming light, which was exactly the effect I was looking for. I just wish there was more pre and post purchase information for the buyer.
