1st big disappointment: A4 format announced is actually an A6: you must fold a 4 A4 lengthwise, or 2 across the width to fit it into the slot. The device was not received in a packaging intact or circled paper was jammed in the destructor. "Following our tests," explained the seller, without convincing me that it was not a returned product or used ... Second disappointment: not very fast, probably due to the thickness of bending required to get an A4. Impossible, so, to make several A4 at a time. And, to top it all, hard to clean pieces of paper stuck. Now let embarrassment new leaves, resulting awry, forcing it to take several times to overcome a sheet.
