So ... tough one to review.  It was an involved assembly, but once halfway through it made much more sense and became easier.  

The day after completion, we had heavy winds which blew it around and bent everything (so we thought).  IT looked destroyed, but when we lifted up and straightened - it went back into shape.  The spikes to hold it down will not help that much - get longer spikes (or what we did was put heavy wood over base poles).

I like it though....
