PROS: sturdy frame, walk through design, easy set up.
CONS:  top holds water and creates bulges. I thought that the curved roof would not allow water to pool, but this is even worse than the traditional gazebo I replaced.  It is ok as a temporary set up, but not to leave put up. Once the water pools it stretches the fabric and creates deep well pockets. 
Too bad, I had high hopes for this.
