Query: Surprised and Disappointed

Bought this shelter based upon the reviews here at Amazon. I have to say after using the product; I am very very disappointed an have already returned it. First it CANT compare in simplicity of setup to the other canopies with folding aluminum framework that are 1 piece. The Coleman is comprised of NUMEROUS different pole pieces that you have to correctly insert into 11 plastic elbows, which are divided into several different groups. After setting it up, it worked fine and looked good. Unfortunately, once the rains came it couldn't stand despite being staked down. Two days latter I went to pack it up. Taking this down is a nightmare and reinforced my decision to return it. The poles are held in with spring clips, which are a pain to indent sufficiently to remove the pole from the plastic elbows. Additionally after one rain, the poles were already showing signs of surface rust.Really disappointed and yet another example of the many many poorly made Chinese products.
