I have looked and looked for a paper towel holder that would be easy to use and at the same time be out of the way.  I say this one in an office I was visiting and went home and found it and bought it right away.  I love the way it is under the cabinet and out of the way of space on the counter and strong enough that it will not bend from use.  The knob on the end is efficient.  Would recommend it highly for all homes and offices.
