I ordered 3 sets of these to conceal and shade our two air conditioners.  They were relatively easy to set up, but don't look like I was hoping.  The very first night it was up, a storm came through and blew them all down.  Being the resin material they were easy to put back up.  I used the extra connector poles to help stabilize the panels by installing them behind a few of the panels.  It did help to keep them in place when the next storm came through a few days later.   If you have a flat level surface to place them on they're going to work better.  These panels really don't work well with slanted or uneven ground.
