Rated 3.0 out of 5 by 3 reviewers.
Rated 4.0 out of 5.0 by good but could be made easier to install I've been using this product for a few years now and it does work well. Just look at the bow in it on a windy day and you can see how much is leaking thru your patio door seals. It is always hard to find the end of the sheet though so I would suggest that 3M put a colored spot or line on the starting edge to make it easier to find. Or put better directions on the box describing where to look for the end in relation to the folded plastic when you first take it out of the box. I did watch the video online but nothing was mentioned about that. I am 65 years old and my eyesight isn't as great as it used to be and I am sure there are a lot of other people out there like me who would appreciate a marked starting tab. January 8, 2015
Rated 1.0 out of 5.0 by Didn't cover my whole door. Useless Box says it would insulate one 6'8"x9 patio door.   This thing barely covered even half of my 6'4"x 6' patio door.  Pretty much unusable.  Upset that I wasted money and time on this. January 31, 2015
Rated 4.0 out of 5.0 by Great Item but not that easy to install on big floor-ceiling windows. Great Item but not that easy to install on big floor-ceiling windows. It could be cheaper by a little but wife must want it installed. Just a very large piece of plastic. Plastics are recycled from other goods. Still a very good product if installed properly. Watch videos on how to install properly. BTW, the package only gives you enough tape so don't mess up or waste the tape by cutting to long. Hope this helps, have fun installing! January 6, 2015
