Worked great for the first year but on 2nd year half of the top showed premature wear.
the picture is sideways shot of the top (roof). It is made with 2 panels. The  one panel  (top in the picture) you can see daylight pin holes though the whole thing and is no longer water proof. The bottom panel is still coated and very much water proof. The roof was subjected to the same weather conditions so that is not a factor here. I need to replace it again but now considering moving on to another product.
