This is my first use of perforelieuse. It is a success, even if I had to start fifteen sheets because the perforation had not done well and had eaten the edge. I perforated and connected to 200 sheets in all. At the end I chose to perforate sheet by sheet because it is actually faster and less risky. By doing the perforation is easy and perfect, it has less need to be vigilant about the positioning of the sheet. In the end I am satisfied and do not ask for more.
