    3M™ Indoor Window Insulator Kit, 5 Windows is rated 2.9 out of 5 by 32.
    Rated 1 out of 5 by from Horrible Not sure why you say you need to use scissor for this, the film is so thin that when I was trying to pull it tight over the window it ripped apart faster then a hot knife through butter.

    Rated 5 out of 5 by from The best plastic for your windows! 3M is the only brand of window insulation that I buy! The tape works great and the plastic you don't even know it's there it really is as clear as glass! I've been using this for years and it keeps the wind from coming through the windows so it really helps keep my furnace bill down in the winter time!!

    Rated 5 out of 5 by from Extremely clear; prevents condensation I have been using these kits on my windows and patio doors for at least twenty years. In my previous house the widows were quite old with major air leakage. In the current house the windows are a well known brand and only fifteen years old but the winters here in Northwestern Minnesota are harsh and the windows are now having condensation issues when it’s cold. I really question some of the negative reviews. As with reviews on other websites, such as Amazon, many problems are due to not reading directions. Their are directions in the box for dealing with separating the layers of film. That being said, 3M needs to have more specific instructions for those who do follow directions. They used to specify cleaning the window mouldings with alcohol. The tape will not stick if the surface is dusty or has flaking paint. Also, the directions need to really emphasize the importance of going all around the window after the tape is applied and making extra sure the tape is secure. The complaints about the tape would indicate that either the surface wasn’t clean or people did not press the tape firmly, as directed. As far as the film not shrinking, again, maybe people need to be told that the film should be pulled as taut as possible. If this is not done it’s nearly impossible to shrink all that excess film. I just finished doing three windows with no problem. I highly recommend this product. Once I tried the major competitor. The tape did not stick well and the film was not all that clear. Using this has saved the expense of replacing windows for the time being.

    Rated 3 out of 5 by from Horrible to seperate Work great but the frustration of separating plastic is not worth it There is absolutely no reason why the fold can not be offset for easy peeling of folds. Time wasted is ridiculous

    Rated 5 out of 5 by from Brilliant Had this bought for my birthday, temps inside were finally warmer than out. Inside was 5 deg warmer than out. No more icicles forming on eyelashes, nostrils and earlobes. Will be doing all windows. Thank you 3M !!!

    Rated 1 out of 5 by from Fiddly, tape doesn't hold / seal 2 person job Bought 2 kits, had to go back to store to buy weather proof tape. The 2 rolls of #m tape were ineffective and lifted easily. When I opened the second kit for patio doors - there was a heat blob which had melted all the way through the plastic layers. Biggest waste of a weekend and money.

    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.
