Incredibly easy to install!! Measuring out the size of plastic need was very easy and I just simply cut it to size. The double sided tape, which is included, is extremely easy to put around the window. The tape is extremely sticky and wasn’t hard to peal away the protective label. Then affixing the plastic to the tape around the window was so easy. To ensure a tight fit, I ran the hairdryer over it blowing hot air to smooth out the wrinkles. The plastic is strong and durable. So far I have had it up for a month and it works well. No more cold drafts coming through.

It seemed thin, but I purchased an air conditioner, and air comes through the vents. I used this and all drafts are gone, keeping them behind the plastic. A great product indeed, east to install. This is an affordable and effective way to improve window insulation during the winter. The kit includes four clear sheets of shrink film, double-sided tape, and easy-to-follow instructions. It helps reduce drafts and increase warmth by sealing gaps around windows. The application process is simple, using a hairdryer to shrink the film tightly. However, it's a temporary solution, and the film may not be as durable as more permanent insulation options. Overall, it's a cost-effective and quick solution for improving window energy efficiency.

This product is easy to apply to windows, but after some time it becomes wrinkled again and needs to be re-hair dryered. Also if the window is drafty, the adhesive can come off after a while. Still, the room is noticeably warmer after using this product.

This stuff is amazing as usual. Don't get to close with the blow dryer or you might burn a hole. This is very simple and easy to set up and it last for a very long time. Will continue to purchase every year. We have also used it to seal our screen door on our camper so that it acts as a solid door. Worked great

I regret i waited so long to get this! It was super easy to install and once you use the hair dryer it's crystal clear! You can't even tell the plastic is there, and my living room was finally warm!!!! I'm sure it will save on my heat and AC bill!

I followed directions for installing the plastic. Very easy to put up size was perfect. Product shipped immediately. Only issue was the double sided tape it came loose on a few windows allowing air to come in. Was an easy fix and I will buy this product again

Plastic film is large, easy to install, I used 1 sheet for two large windows. Film seems very thin but sturdy, it keeps draft out & allows sun to come in. Presently a consistent 12° and very windy, artic blast is forth coming, that shall be my test

It was very easy to install. In every other kit i bought, the supplied tape was a pain to use, but in this kit, it was very easy to peel the tape without wrecking it.

So I did this to my window few days ago. It looks like hell, it’s hard to install (tricky) , you’ll never get it looking perfect, the double sided tape is hard to peel and work with. It’s a crazy amount of money for cheap plastic you could have bought at the dollar store. You can literally do this yourself without this kit and save money. Just get double sided tape and plastic and away you go. Also, it did NOT stop the moisture on my windows. Somewhat of a scam but maybe it’s meant to stop the draft, even though the website says “no moisture cause moisture will have no where to go†and next day I still see moisture on windows lol. I tore it all down it looks like crap and doesn’t work. I wouldn’t recommend you’re better off buying a new window if that’s what you need . Forget this idea .

The included tape was literally useless. Entire kit went in the garbage. What a ridiculous waste of materials all because you wanted to save 0.00000002 cents per roll of tape.
