Wish it had sturdier posts.    The holes for anchors are too small for 1/4" anchors.   Had to use 3/16" anchors.    The difference is significant.  1/4" were bolts.   3/16" are screws.  Now I have to redo it using concrete adhesive.   The stakes are useless on concrete pad.  Instructions to take this down during windy conditions is really dumb.   I am installing for permeant use.
The top roof installation required excessive stretching before the cup would reach the end of the arm.  I made a tool with a hook to pull the fabric cup while also pulling on the fabric pull loop.  After three days it finally made it fit.  It would be nice to have 4 light fixtures, instead of two.  The two wire racks are predrilled for center mounting.   It would be nice for pre-drilled holes in case I want to flush mount the racks to the inside or outside of the posts.
