Labeling is wrong
We were looking for a plastic covering for a large patio door that was 12' wide. When looking at the product packaging it says it's for extra large windows with no mention of patio door applications. After looking at the specifications on the box and comparing it to a patio door product it was obvious the sheet was the same size as the patio door plastic. The box should say on it that it will work for an XL window OR patio door.

Wrong Size
I bought this expecting 6 ft 8 in x 19.5 ft. The product inside is not even 4 ft wide...although it is the 19.5 ft long. Hopefully stripping the window will seal properly...Bought Nov 2017

    I assure you there another layer
    When opening the package I experienced the same concern as the 1 star review. I thought I was ripped off and the plastic wasn't 6'8" but after 30 minutes of messing with the plastic I managed to separate the layer and unfold it into the proper height. After that everything was fine, but the it was really hard to find the seem and separate that layer..

    Film too short
    I work at a hardware store in town and sold the window kit to a customer for her windows. She brought it back saying it was to short, we examined the product and it was to short. It shows that it should be 6'8" but was less than 4'. We opened another package of the product to check it. It was also too short.

    DO NOT BUY... FIlm is TOO short
    The film that came in both of my packages is 3 foot 8 inches and NOT the 7 foot that it promises. I opened two different packages and the same thing! THis is frustrating and I have had to go back to different stores numerous times to buy, rebuy and return. DO NOT BUY THIS MISLEADING PRODUCT

    Great product
    This is a high quality 3M product that you can purchase from Walmart for much less than the unknown brands in the hardware stores. This is a very long piece that can easily cover two large windows (almost twenty feet) It is perfectly clear and the 3M tape holds extremely well. Highly recommend.

    Works Very Well and Easy Installation
    I have used this product three times in three years. It is perfect for my very wide 4-panel patio doors. I agree it would be nice if the box mentioned that it is big enough for this purpose. The reviewer who thought the product was not sized as promise has my sympathy. The film is very thin and it can be deceiving when unfolding it. That is why the company include a little sheet with a suggestion for the best way to unfold the final flaps. Works perfectly. I suspect he or she was not able to discern the need for one more unfolding. Overall, an excellent product.

    Snug and warm......
    This window film installs easily and seems to give us quite a bit more insulation. We have 4, large windows in the front of our home, which is in the mountains of Idaho. The windows are 4 X 6 and 4 X 8 feet. The tape and film went on easily by installing the tape around the window trim, and then starting to peel the tape at the top corner, and after tacking one corner of the film--just slowly removing it across the top, and then down each of the other sides. It easily pulls off for readjustment and tightening. It helps to have two sets of hands while tightening the film. We didn't even use a blow-dryer to shrink the film--it is tight enough from hand adjustment.
