Rated 3.4 out of 5 by 43 reviewers.
Rated 1.0 out of 5.0 by Avoid at all cost I spent about an hour cleaning/dusting and applying 4 of these to my windows and by the time I finished the 4th window I noticed that the first 2 has completely let go, I went to HD and got a full return on the 3pk and 9pk I had purchased and instead got the 3M kits like I had planned in the first place. Don't try to save a few bucks, get the better quality ones, unlike myself who is now redoing all the windows I did this morning. Boo October 31, 2015
Rated 1.0 out of 5.0 by Does not attach to window I applied this film to 10+ windows. Each and every window had the film detach. I had to remove the film and the tape and replace it with 3M tape and film. The 3M stuff works beautifully. DON'T BUY THIS STUFF!! October 31, 2015
Rated 5.0 out of 5.0 by A clean surface is the key I live in Upstate NY where the winters can be brutal. I have been using this product for several years now with great results. I have found that the key to successful use is that you must make sure the areas around the windows you are planning to cover must be absolutely clean and free of any kind of dirt, dust, grease or grime, including any cleaner residue. I have found rubbing alcohol on paper toweling works the best to do this. You may have to clean around a window twice, depending on it's location (i.e. a kitchen window). Allow a few minutes for the alcohol residue to dry up and the tape sticks very well. The savings I see on my heating bill are way beyond the cost of the product. Well worth the money!

Rated 1.0 out of 5.0 by Worthless! This product is a waste of time and money. Followed instructions explicitly, but tape did not stick, and plastic expanded within hour or so after it had been installed. November 17, 2015
Rated 5.0 out of 5.0 by Drafty windows - No Problem! I live in an apartment with old, drafty windows. It gets ridiculous during the winter. Cold air just pours in through these windows. After applying this film which was a snap, no more drafty windows! This kit makes it easy and Home Depot has kits in all sizes to cover all applications. Thanks Home Depot! November 14, 2010
Rated 4.0 out of 5.0 by No problems I went with this brand because it was the only one available. I had never tried this type of product before so I did some research before using it. It's important to make sure the area you will be applying tape to is clean and dry! I think some reviewers who had trouble with the tape may have skipped this step. I followed directions online by mixing equal parts water and rubbing alcohol and wiped down my window frames with this and let it dry. The tape was sticky, but not so sticky that I couldn't lift it off to reposition it. I put tape around the entire window and let it set about 10 minutes to make sure it was stuck well. Then I took off the backing, pressed the plastic sheet on the tape - starting from the top middle of the window and stretching to fit. You can lift and adjust the plastic until you're happy with the placement. Then I took the hair dryer and began at the edges, working my way around the window and then inward to the middle to get out all the wrinkles. Don't keep the hair dryer on any one area for too long or you could melt a hole in the plastic, keep moving around until it's tight. That's it! I just recently purchased this product and I've only done 2 windows - a regular size window and a large picture window. The regular window was easier and the edges are much smoother. The picture window would have been easier with 2 people, but I made it work by myself. Overall, this product is pretty clear after it's applied. There are some crease lines in the plastic that just won't come out no matter how much heat I put on it, but it is not that noticeable. I'm hoping that I will notice some difference in our utility bills, but then I'll probably be kicking myself for not doing this much sooner since it was so simple! July 12, 2012
Rated 5.0 out of 5.0 by Works GREAT!!! This product works fantastically!!! The double sided tape didn't stick that well at first then I wiped down the widow frame with ammonia and presto it stuck like... tape... Keeps my bedroom warm no more plugging in the heater all I need now is a blanket and I am Good! December 13, 2010
Rated 5.0 out of 5.0 by NO MORE DRAFTS! This is NOT a labor intensive project. Actually its very easy if you allow yourself the time to do it right the fist time. In my case the windows took about 30 mins or less and the slider took about an hour. It goes pretty fast once you get the hang of it and you can keep the surfaces warm enough for the tape to stick. Take your time and the process is easy. * Remember to wash interior window prior to putting up film. You won't be able to until you take down the film. After reading all the reviews I recommend the following. Do whatever works for you. 1. Clean area where you are placing the tape with rubbing alcohol for best sticking of the tape. 2. Use the hairdryer to dry the area you just cleaned and this also warms the surface so the tape will stick better. 3. Apply tape (take your time) 4. Before removing cover on tape go over with the hairdryer and press it down again . (heat helps tape to stick) (It's cold outside and the windows are cold too.) 5. Apply film per instruction on box. (Take your time) 6. Follow instruction on box to shirk film. This process results in great clarity. Use that hair dryer to keep the surfaces warm. I noticed the tape sticks better to the window casings and to the film when it is warm. It is really worth taking the extra steps when applying this film. Then enjoy no more drafts from those windows for the winter. I might do it again to help with my cooling costs in the summer too. I covered my single pane windows and the slider window where the draft would move the vertical blinds. I notice an immediate difference after doing each window. I am very satisfied with this product.
