Broke upon second use
Color: Navy Blue, Size: 9ft
The umbrella never really opened right. I wasn't sure what the problem was, but today it's completely broken. The crank (which was installed incorrectly to begin with) doesn't do anything. I've only used it a couple of times, and I'm 2 days passed the return window. Very disappointing. It is nice looking though.
