    3M™ Indoor Window Insulator Kit, 5 Windows is rated 3.0 out of 5 by 36.
    Rated 1 out of 5 by from Lots of tape residue The tape works well but when I removed it in the spring the tape left a lot of residue. It is supposed to come off cleanly. I have not found a good way to clean it off my aluminum screen door

    Rated 4 out of 5 by from Problem This Year Only We have used ONLY 3M Brand Window Insulator Kits for the past many years. This year, however, there was a quality issue - it looks like scratch lines in the film. Local retailers were out of stock on 3M and we were too late to return it to you. Obviously this was a production problem. We are not happy with the appearance and never had previous issues with the product.

    Rated 4 out of 5 by from Works Really Well, However I've been using this brand of insulating film for several years. It works well in keeping the cold at bay. Last year, I noticed that after a few days, the film gets a cloudy mottled look to it. It turns out that the cloudiness can be wiped way with a light touch, but comes back a few days later. I have had the film kits for a few years, so it might have something to do with the age of the kit. All in All I am happy with the product.

    Rated 5 out of 5 by from Fantatstic product I've been using these 3M window insulator kits for three years now. I insulate approximately 15 windows in my house each winter. Applying these kits is simple once you get your process down. The tape is Scotch tape and superior to any of the other brands. It will not leave nasty sticky residue on your windows/woodwork when you remove it. I know that they are working because they will inflate on a windy day with no drafts. You will witness a bulge in the plastic as if it were a sail on a boat. What you are seeing is the cold air that is not entering your house as a result. I highly recommend these kits.

    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
