Tension rod does what is expected.  I would advise caution however.  I have it spanning 100" with shears only.  With that span and the tension applied to keep in place it will droop a bit in the middle.  I plan to get a retainer for center support from hardware store.  Otherwise, its great.  The only other thing worth mentioning is the rod itself is around1.5" not the 4" as mentioned.  I think the 4" is measured from the rod end pieces (which are removable with small Allen wrench enclosed.
