The mechanism is a heavy duty aluminum and it works well. Opens and rotates easily. They look great too. Very happy with the quality and price. It is a great value.

We live in Arizona where the summer sun is unbearable, even when in the pool. After looking into getting a shade sail installed, we opted to get one of these umbrellas instead and it is perfect because it’s attractive, well built, and easy to operate. I especially like all the different ways it can be adjusted. We chose a base with wheels, so in addition to adjusting the umbrella as the sun moves, we can also easily roll it to be used in any area of our yard. Much more flexible and more economical than a shade sail.

We've been using this for a few weeks now and it's exceeded our expectations! It was easy to put together and is so easy to use! I'm just 5' 3' and can easily put it up and take it down I can even manage the cover Love the ease and convenience of the tilt function and 360 swivel! Definitely recommend!

Wonderful umbrellas We love the shade They provide swimming in the desert community enjoyable great product

The umbrella is well constructed, easy to assemble and performs as advertised I'm not able to keep in in my particular environment I live along a pond with a fairly steep sloped bank We've had unexpected high wind gusts which prevent the umbrella from closing I believe the wind is driven upward and the umbrella is held open while I try to crank it down On 2 occasions it's caused damage Both times, I received tremendous help from your support team and from Tears in particular She sent me the correct parts with no issues and the umbrella was very easy to repair back to factory condition It's a good product It just did not work our for me
