Broke a sweat putting this up.  I wish all tension rods came with a hot guy to twist them into place... let the hot guy use their hands over their heads until their biceps burn to put this thing up... anywho—
It’s a tension rod. It’s stays in place and holds up a shower curtain.  Not sure what other feature you’re looking for in your tension rod hunt... but this baby is a rod, that has tension and holds up a shower curtain.
