Overall it works but, we had the roof pooling water that it actually bent part of the frame.  We were under warranty and fortunately were able to replace the broken part. The roof still got stretched when raining but we bought seperate clips used in fabric greenhouses that clipped onto the roof along the beams and so far so good.  Unfortunately, we now have the screen on one corner where it has ripped from the base and will be contacting for support on that as well.
