The black metal perforator met my expectations fully. Thanks to a very helpful review I have at the beginning, taped after setting the correct hole spacing for my Filofax, the open holes in addition to punching with adhesive, so I distribute no confetti in the office. The holes are accurate, no cracked edges. The punching is simple and the fact that no 100sheets suddenly possible was based on the product description does not surprise. In addition, the mass processing is necessary only once a year, because I print my calendar and einsortiere. Bottom year falling just individual pages that need to be inserted. Therefore, Thumbs Up, super punch and for the price there is really nothing to complain about!
