I bought this product in 2012.  Its gone thru 6 Noreasters and multiple winters with winds as high as 95 km/h and has never had a problem.  It holds up fine to the salt water weather we get in the fall and winter really well.  I had one hiccup installing the floor panel at the door panel but will finally fix that this summer.  After 6 years I can honestly say that you definitely get your money worth with this product.  What a great investment.  Irt looks sharp and the panels are holding up extremely well.
