I ordered it to use as a sun shade for a group of older master gardeners who teach gardening to grade schoolers. We are out in the Florida sun with no protection from the sun for 3 hours. This product has saved us all. We put it up for the classes and take it down to store it afterwards. Thus, we do not bother to tether it to the ground, and it has been quite stable even with some heavy wind gusts. It is definitely not a one person set up or take down; but two woman can manage both without much of a hassle.
