It staples well, though you have to be careful with 2-4 thin paper sheets, as staples can be bent back through the upper surface. Works well with both Rapesco & Rexel staples. The arm can sometimes jam half closed after a staple has been fired but it doesn't actually jam when stapling. Firm not high pressure is needed in operation. It's light in weight, easy to find on the desk, the mouth is 8mm wide and the magazine will take a full strip.
I have had this stapler for about 6 months now using it everyday in an office environment. It has not caused any problems at all and shows no resistance even when stapling quite an amount of paper. Overall very pleased.
Works fine, stands out as a little different in the office so it won't get pinched or I can track down who has taken it. Built down to price, but still recommended, came with staples which surprised me. used for 2 weeks in a office.
