    3M™ Indoor Window Insulator Kit, 5 Windows is rated 2.8 out of 5 by 26.
    Rated 1 out of 5 by from The never shrinking plastic.. Bought this for my large dining room and kitchen windows to help keep the rooms warmer. I was very excited to use the products. But the plastic would not shrink! So frustrating, especially after all the time I took putting up the film and attempting to blow dry it.

    Rated 1 out of 5 by from Plastic will not shrink 3M clearly had some quality control issues because film will not shrink. I am not alone several other reviews experienced the same thing. Very disappointed. Wasted time and money.

    Rated 1 out of 5 by from Horrible tape I attempted to use this just a moment ago, and the tape doesn’t adhere at all. After wasting a strop the length of the window because it didn’t stick, I tried smaller steps all around the fram and all came loose within minutes.

    Rated 1 out of 5 by from Frustrated Cutting this giant piece of film has been impossible - I wasted three pieces, and therefore my money. Typically a big fan of 3M and this has been nothing but a giant headache!

    Rated 1 out of 5 by from Worst double sided tape possible!!! Bought this kit one week ago and the tape already let loose. I’ve experienced this a year ago and thought I would be smart and put two strips of tape 90 degrees from the other and they both let loose on both strips . No I would never recommend this window kit to anyone PERIOD!

    Rated 1 out of 5 by from Quality has gone down We have been using 3M window kits for over 14yrs with awesome results. This year however, the plastic will NOT shrink. We returned the 3 boxes we bought (thought maybe they were old), bought 3 more. Exactly the same problem. Over heated by blow dryer trying to get it to shrink. NO LUCK. So unhappy with this product. I don't know what cost cutting changes they made, but will look for other brands to try

    Rated 5 out of 5 by from I love the product I've used the film for years and always satisfied with the performance. Keeps nasty drafts out and easy to put up. Only problem I have is separating the tape when I do, I fold it over so I can use it again without the hassle.
