Yes, you hold it upsidedown to see the circle you are cutting. Plus, I oversize the printed number cards by 0.05" - that is, they are 1.55"in diameter. This is easy to do in PowerPoint. Thus, you don't have to be as precise in positioning them for punching. If they were exactly 1.50" in diameter you spend an inordinate amount of time positioning to avoid any slight white portion appearing on the punched number card.
