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…

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.

AMAZING PRODUCT!

I am so impressed by these! It’s winter and my skin has been so sensitive, dry, flaky patches… I’ve tried so many products! I saw a few videos of these being used decided since there were so many independent videos about them I’d try! O.M.G!!! I should have taken a before and after! After only 1 use my face feels sooo much better. No more dry, flakiness. They were extremely easy to use. I have a bit more of a round face and they fit just fine (went up a little higher on my hairline but not bad). Doesn’t leave your skin feeling sticky, just hydrated! 100% will buy again!
