I bought this clear vinyl for the purpose of winterizing a section of my deck.The quality seems good, which is definitely the most important factor to me, but I will have to see how it holds up through a Wisconsin winter.I ordered the 8'x20' size. I was disappointed to find out it was just short of 19' in length. I really needed that extra foot to completely close in a side of my porch, however I am still able to work with what I have so it's not a huge deal.I was afraid the vinyl would distort the view or make it cloudy looking outside, but it is very clear, there are just some deep wrinkles that will be difficult to get out, but again that is no big deal.Overall for the price I am impressed with the quality and it looks like it should hold up pretty well to the outdoor elements.
