Easy to put together. I like that you can choose to assemble them vertically or horizontally. They also come with two choices to anchors for the bottoms—one for concrete and one over soft ground or gravel. They seem sturdy and look nice. 
I’ve ordered 5 to surround two sides of a gazebo. Hope they can provide a little extra shade and block some rain. 
We’ll see how they weather in the harsh Florida sun and hurricanes.
