So far we are very happy with this. Our old curtain rod broke and we were doing some improvements anyways, so time for a new curtain rod.  This is more than I would like to have spent, but so far worth it for us.  The curve isn't huge, but we have a TINY TINY bathroom and tub/shower area.  Nothing is "normal" sized.  This actually made a quite a bit of difference from the old curtain rod and now getting a shower is much easier to move around.  I'm very glad we purchased it.  Also, depending on how much room you have, it can give you different amounts of space.  We put it up as far out as we had wall and if we had a bit more wall there, we probably would have set it out just tiny bit more for even more room.  So over all VERY happy so far with this purchase.  I didn't think you would be able to buy the curved rod with the tension option.  Awesome!
