Input:
Had a Tiffen that I paid $40 for years ago and loved it, but it broke.  Ordered a new Tiffen for $20.  Turning it is so tight that it throws off the focus.  My old Tiffen did not have this problem.  My Hoya does not have this problem.  This problem is unacceptable since its impossible to tell the polarizing effect with the lens out of focus.  Returned it for a new one and same thing.  Quality control is gone for this product.  Amazon will pay for the return if its within 30 days I believe.  Beware
