PURPLE LEAF 9ft Outdoor Square Cantilever Umbrella - Heavy Duty Windproof Offset Patio Umbrella for Garden, Deck, Pool - Perfect for Shade and Sun Protection (Black)

In a nutshell - the umbrella is great. So glad we got it.We live on the Columbia River facing south/southwest across from a wildlife refuge, so we need some shade but I didn't want anything that would permanently block the view. Also, we're near the mouth of the famously windy Columbia Gorge, so any umbrella would have to be extra stable, even when closed (I've lost several tall, heavy potted plants).This umbrella hit every mark. 1. As you can see from the photos, when the umbrella is closed, it's out of view. 2. I can sit outside now and find shade any time of day by changing the angle of the umbrella. 3. My engineer husband laughed at me when I said we ought to move it to the side of the house to be safe when the big winds come. He said that the umbrella is going nowhere when closed. We had some 15 mph gusts the other day when I was sitting outside, and there was some minor movement at the top, but nothing to be concerned about.Assembly and operation: My son put it together on his own, pretty intuitively; however, he's 6'5". If you don't have the height, It would be pretty difficult without two people. Now that it's assembled, it's very easy for me to put up and down and change the angle.We got the moveable base because I wanted to be able to adjust the location to shade the table or the seating area. However, we filled it to the max with sand and water for maximum stability, so it's big and it's HEAVY. My son and husband can move it. I (a fit 135 lb, 5'5" woman) cannot. Customer service suggested we take some of the sand out and put a couple of sandbags on top instead. We'll do that before next season.
