Great Buy for quality & price
I've bought many patio umbrellas over the past 22 years and must say this is the best yet. Not just in quality but also price. I bought the 10' & it's the perfect size for my patio, I've sat under it a couple of times in the sun & the sun never gets through to me. Plus, I'm 75 yrs. old & had it put up in about 5 minutes. Great buy

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.
