Rated 3.6 out of 5 by 40 reviewers.
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 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 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.

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 1.0 out of 5.0 by Worked for a day I bought this and the patio door kit to help with some old windows/doors. The tape took significant time and multiple attempts to adhere properly to the trim surrounding the window. The plastic attached nicely at the start, and the plastic pulled tight when heated (as per the instructions). The next morning, however, the plastic pulled away from many taped areas leaving large gaps and permitting drafts to enter. In the end, this product did not function long. Additionally, repair of the gaps will require replacement of the entire plastic sheet as the plastic is now too short to reach the tape. As with the patio door kit, I feel this was a wasted effort.

Rated 5.0 out of 5.0 by good product trying this out for the 1st time this winter season and so far it's stopped the draft I was getting from the window December 17, 2013
Rated 4.0 out of 5.0 by Works fine, as long as you clean the window really well These work fine, as long as you make sure to clean the window frame very well. Even if it looks clean, you should still wipe it down with a household cleaner. Otherwise the tape doesn't stick well. November 19, 2013
