It is new so I can't say how durable it is.  I had a different brand before but it did not have the top supports that this one has.  The zippers seem to be as good as my other one with the exception of the door zipper.  I liked the tie back design.  I had to lag bolt it to the deck I built for my hot tub before I could push up hard enough with the help of my girlfriend to make the latches catch.  Sides were easy to put up.  Liked all of the velcro that secured the top and sides to the frame.  Other than having to bold it to the deck and it took 2 people to get the 4 corner frame latches to engage, it is great.  We will see how it stands up to the elements.
