I was actually pretty disappointed with these. I didn’t realize they would be PLASTIC. The knob at the end is plastic, not metal.  Also, the packaging was pretty beat up, and some of the rods were slightly bent.
In the end, rather than go through the hassle of returning them, I still used them.
From a distance, you can’t tell they are plastic, so it’s fine. 
If I had known though, I would have went with something else.
