Nice Umbrella for the Price
Size: 9ft, Color: Red
Truly surprised at the quality of this umbrella. Great deal for the price. I did see some reviews prior to buying that there were issues with the tilting mechanism/crank so I am giving it a 4 until I have it for more than a few days to see how it all works out.

Honestly impressed would recommend
Size: 9ft, Color: Beige, Size: 9ft, Color: Beige
I’m honestly really impressed with this patio umbrella! It’s lightweight enough that it was easy to move and set up, but it still feels sturdy and stable once in place. The fabric material feels much nicer than the cheap plastic-like material some outdoor umbrellas use — it looks clean, durable, and gives really good shade.
The color is beautiful and works perfectly with outdoor spaces without looking harsh or too bright. It opens smoothly, provides a large amount of coverage, and has held up great in the sun and wind so far.
Definitely a thumbs up from me — great quality for the price and makes the whole patio area feel more relaxing and put together! ☀️👍

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.
