This is hard to install.  The poles will always try to skip back down by gravity so it’s hard to put it upright at a good enough tension.  Then give it enough time, in my case, a week, it collapsed.  More interestingly, the connection point of the horizontal bar also breaks off.

After the collapse, the poles get stuck in length and cannot be adjusted.  The whole thing is now rendered metal waste at my home.

Good concept, bad execution.
