If you read reviews, then one finds everywhere against. In the case of this Langarmhefters is suggested that the staples come when pamphlet stapling is not exactly in most formats in the middle. The reason is stated that the stapler can not be adjusted continuously (on the ordinary DIN A-formats and the center of the leaves). In fact, the stapler engages in the possible positions, which is a continuous orientation prevented. Only: The stapler snapped completely correctly in the correct positions and sets the staples very precise. Create DIN-A-5-brochures, and since that's 100 percent. In this respect, there is absolutely nothing to complain about for me at the Leitz-unit at the moment. Now it must prove itself in the long-term operation.
