Review on 🪟 3M Outdoor Clear Window Film: Insulation Kit, Heat & Cold Protection for Two 3 ft. x 5 ft. Windows by John Roberts

I have 2 very old windows that are very bad in winter. They usually get covered in ice (from the inside!) it's that bad. I installed them in November (now February). This weekend we had lows of -18°F and no ice formation. The glass is just a little cold. I used the tape that came with the kit. I'm pointing this out because I remember other reviews saying something else to use, but I've had no trouble installing this and it's been 3 months now. I need this for 2 more and I fully expect they will. I will buy it again so I'll be ready for next winter.
