3m Window Kit 84" X 237"Film

3M brand is the only kit you should buy. It works great. The tape sticks but can be removed in the spring. Once you get the hang of installing it, it looks wrinkle free and clear. I mainly use it to keep condensation off my bathroom windows. They would always fog up and would sweat/freeze damaging the wood windows. Works great.

Installation wasn't too bad and was very clear and my wife couldn't tell I put it up until I told her. Does it save energy? I don't know, but it does cut the draft from my windows pretty good.

I would get the same amount of tape with smaller kits, so of course I ran out which is unfortunate. But, the film is so much higher quality than other brands. 3.5 stars.

Unfortunately have to use this every winter because of our window. Works great! Clear viewing after application unlike other brands. Highly recommend. We use every year.

This the best and only window seal kit you should buy….one made by 3M. Any other brand is no good. Their tape goes on and comes off easy and the plastic is crystal clear and shrinks up great.

What a disappointment. I've used this product for years, but this year 3M decided to cut cost by cutting quality. The self-stick tape is not as wide and thinner making it darn near impossible to separate from the its paper backing. The clear plastic itself is thinner making it harder to work with.

3m is the best

It takes a little time,, the cutting and taping, but it's worth it if you do it correctly.

I had aluminium windows that have condensation when temperature drop down under 10 degree. After putting the film on, no more condensation. Loving it.

It sure stopped the cold air . Need more for the rest of these old windows I have

Second to none. Don’t use duck brand, hard to see thru and usually lets go before spring. Never had issues with 3m products

3M is the best ...... and I have tried them all.

Don't waste your money on this product. 3M USED TO (15-20 years ago) make the best Crystal Clear window film and it would shrink very tightly to produce an invisible window film. What we purchased and installed this week was garbage in comparison. 'Clear' is not a word I'd use to describe this let alone 'Crystal Clear'. Better install it tight as well because it does not shrink well with heat as directed. We tried Home Hardware brand which was of the same disappointing quality.
