We bought these for shade shelters for our goats and they worked great. We lost them in a tornado so we put up a couple more. We had to do it in  somewhat of a hurry and my husband didn’t screw it’s all together like he did the others so we lost them to hurricane Barry. I think if he had screwed it together, they would’ve been fine. I plan to order these again but screw them together again. It doesn’t come with the screws. We just did that ourselves. These are super easy to put together and easy to move. We got heavy duty spikes to keep them in place and my goats (Pygmies) didn’t move them when they rubbed in the poles.
