papers MUST be pulled straight and taught with both your hands before it triggers. Sometimes you can get away with a one handed stapling but usually you sit there jamming it in and out 10+ times before it detects it.oh, and it is LOUD. Ridiculously loud piercing snap with a ring afterwards. The loudest thing that ever happens in the office is this stapler. the whole office can hear it. Tried dampening the noise with dynamat, didn't help at all.Staplers should be easy, not hard. This is simple stuff, I thought this was a premium product to make my office a bit nicer but no.I even tried buying "premium" staples that cost 5x as much and come in a special little tin, that didn't help. Tried cleaning it with q-tips, nothing works.donotbuy
