Brightens up the whole patio!
Size: 9ft, Color: Apple Green
I am so happy with this umbrella! The "Apple Green" color is gorgeous—it’s super vibrant and really makes my backyard feel more tropical and fun. The crank is smooth and easy to use, so I don’t have to struggle to get it open, and the push-button tilt is a total lifesaver when the sun starts to dip in the afternoon. It feels much sturdier than the one I replaced; the ribs seem solid and it hasn't budged during our usual afternoon breezes. It provides a ton of shade for our table, and you can tell the fabric is thick enough to actually block the heat. If you want a pop of color and a reliable umbrella that doesn't cost a fortune, this one is perfect!

Mostly well made…
Size: 9ft, Color: Dark Blue, Size: 9ft, Color: Dark Blue
The umbrella itself is made out of great fabric and the color is accurate to the photo. However, we’ve had it for less than a month and the piece that controls the angle of the umbrella has already broken off. It still works, but will always be at an angle now.

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
