Rated 1 out of 5 by from Couldn't put up alone I measured the plastic for my window, as directed, but was unable to put the window cling up by myself. I really needed a second person to attach the second side tightly. Yes, there are tapes to hold it to the windows, but to get a really tight hold you need to stretch it before putting the tape on

Rated 3 out of 5 by from Great idea 3 M gave me a sample of this product to evaluate. They took a while to figure out how to install, and we were only able to install on the lower part of window. The hair dryer did not entirely work.

Rated 5 out of 5 by from Excellent for drafty windows in the NE I live in Philadelphia in a loft style condo in which my landlord doesn’t care that the old window needs to be re sealed and glazed. I have used this for a second year on a row and the difference is dramatically different with it installed. My heat runs constantly without it due to the draft, with it, dramatically less and I set my thermostat to 68. Before installation I can barely sit in my living room because the draft is so cold. With this product my apartment is so much more comfortable for the winter months. The tape and plastic holds up all winter long for 3-4 months. Second year using this and love it !

Rated 2 out of 5 by from Works okay, but not as claimed I have used this product for several years. This year I purchased another kit to insulate my windows. All worked well, but the film has numerous creases in it that do not come out when shrinking the film with the blow dryer. So now all winter as I look out my windows, I have to see creases. Attached photo shows them, though it's hard to capture with sufficient contrast to make the defect stand out.

Rated 5 out of 5 by from Worked great! We have old wood windows and most of them have storm windows on the outside but one window doesn’t and every winter it gets so cold in that room and the window gets condensation and frost on it. We used this insulation kit this winter and it’s making a big difference! No more drafts and less condensation. It was very easy to use as well. So far we are very happy with the results!

Rated 3 out of 5 by from Works Great I received this Window insulator kit from 3m in exchange for an honest review. This was my first time trying this brand for window insulation and I was a bit disappointed. We did not need them right away because of the warmer temps but as it got colder we applied them to 3 windows. First off if you have cats who have pica this is not a great idea because they automatically go over and start eating it. The instillation was very simple however if you have hot forced air with the vents directly below the window they will not stay stuck for very long. The tape just doesn't hold up. It does not destroy the plastic so you can just go out and buy a painters tape and add that to the outside to keep them stuck. They do as they say though and actually keep the rooms they are applied in warmer than without so I would recommend these to people but suggest having an additional kind of tape available and keep away from cats who eat plastic because they will keep your rooms warmer!!

Rated 5 out of 5 by from Great at keeping in heat So I've had this a while and didn't want to review until I could review it correctly. I put this on my bedroom windows to keep in the heat and keep the cold out. It definitely delivered. The plastic is plenty thick enough, it is very easy to use and comes with everything you need to prepare 2 windows for the harsh temperatures that winter brings. This product is well worth it and I highly recommend.
