For me, a totally useless product, which also is not exactly cheap. There is a plastic punch that really only 1 side thin paper punches well. Thin card, or even two sides normal paper are wrinkled, because you had to press very firmly and it not working. Other crease formed in the paper when you want to open the punch again, because it locks in the drilling operations. All in all, not recommended. 2 stars for the possibility An insert in the Filofax.
