The "spines" that hold the fabric are made out of tin foil. The very first time I opened the umbrella, one of the support rods bent. I figured it's a simple fix: bend it back in place.....NOPE! I started to adjust it but it felt so frail, I just left it as is. I bought the 5 year protection plan to cover all bases, but Square Trade refers me to the Wayfair website to have the situation resolved. But you can only speak to a customer service representative (that you can't get a hold of) so needless to say, I am extremely disappointed and frustrated by this whole issue. 
UPDATE: a Customer Service Representative called me back less than an hour after trying to get through. She refunded the full price thus the amount of the protection plan. So all in all...not a completely bad experience.
