Very Impressive Performance / Resiliance AND Super Simple Removal
Oct 2019: Purchased this product to cover large screens for older, larger condo insulated windows (30" x 50"). Was a little surprised that these were not heat the shrink type that I've used before for interiors. But the product was easy to install (took me about 15 minutes per screen), was easily able to stretch out wrinkles, and no problems unfolding / peeling the plastic open. There was actually enough double sided tape for 3 of my windows, plastic covered two. I've got some larger windows still to do, had to buy one pack for each of those, using the plastic sideways.I did my best to secure the tape to window (pressed around the screen frame with my thumb several times) and similarly the plastic once it was affixed to the tape. If it holds up, should do a good job creating a second vapor barrier and cutting down on drafts.May 2020: Removed the plastic this afternoon. First, all six plastic sheets were intact after a New England winter. Second, plastic removal was beyond simple - the plastic peeled away from the tape easily. The tape needed a little encouragement but by and large came off the aluminum frame in one piece and with no sticky residue. I'm a little shocked at how much of a non-issue removal was. I'm a fan for life!

Great results
I was able to do 2 of my windows and used whatever was left to tape up and cover a third window. I wasn’t sure this was going to work but it is amazing how well this has worked. I no longer feel the cold air coming thru. I’m poor so I can’t afford to be buying fancy windows, but I’m glad I’m poor. I used to work for someone rich that didn’t care about her employees and that’s not how I’d want to be. Better to be poor than to have money and be mean.

Excelent product!
It cover well the windows but I waisted too much of the plastic trying to make it fit by following the instruction saw on the listing video, mostly It does requires to seal air filtering spots with others products before to use it, good quality, ease of removal, Value for money it's ok.

The glue tape does not work
Easy to assemble, work great, but the glue tape is not strong enough. Due to airflow leaks in the window, pressure builds up and the glue of the tape is not strong enough.

An ounce of prevention
This will be my second winter installing these things. Note there are films you apply to the exterior of the window and films you apply to the exterior. These go on the EXTERIOR. I have small children and don't want them fiddling with the films and i worried about interior films fitting under my Venetian blinds. I prepared for these to be a major pain in the posterior to install and braced myself for hours of the film folding over on itself and working out creases. Boy was I wrong. It actually wasn't all that bad. I covered nine windows in about an hour or so. If there is a glaring crease, it is easy enough to pull the film off of the tape and straighten it out. They held up from early November to May with no punctures or tears. It has the pliability of saran wrap (it stretches) but is not adhesive so it doesn't get stuck to itself. You are not supposed to install them if it is below a certain temperature outside (I think 50 F), so don't procrastinate. I don't know what happens if it's too cold--I'm guessing the adhesive doesn't adhere as well. They tear off in one easy piece in when you are ready to take them down but the double-sided tape will stay attached to your house. I should have scraped it off but let it stay there so I can't say how hard it is to remove. My gas bill dropped in half but I don't know how much to attribute to these alone because I added these, along with a programmable thermostat and power outlet insulators, at the same time.

This product failed miserable. Waste of money.
I purchased 6 of these kits to cover all the windows in my home. These are the exact same kits I used last year with excellent results.This year, I applied the product on a warm CA day (72 degrees F). They went on easily, like last year. Unfortunately, every single window covering pulled off within 24 hours. The adhesive tape was a complete failure. No rain, no drastic weather changes, only product failure to blame. I ended up removing them all and throwing them away.Perhaps they changed the adhesive? I've always had good luck with 3M products before, but this was a complete waste of money. Never again. Beware.

Works great even in high winds
I have a window leak and while I’m waiting forever for the warranty repair this has been a life saver. The tape is strong and held the plastic in place even though 2 windstorms so far.

The MOLLE sheath is of exceptional quality. Very happy with my purchase.
Specially developed 3M tape and film system for outdoor use. Clear as glass insulating film installs easily from the outside. Stretches drum tight and wrinkle free. Fights air infiltration and adds an extra pane of insulation, preventing frosty windows. Special weather resistant double stick tape included.
