Spectacular App!

This is the greatest, most fantastic app I have ever downloaded! The user interface kept my attention riveted to the screen as I input the outside diameter of the penetrating pipe into the well-defined user input field. I was then treated to another overwhlemingly joyous experience as I input the diameter of the wall opening. The solution provided a completeness to my life that can only be described as spiritual to the extreme.
