Not that I had it in continuous operation, but I use the thing quite often. I ordered it because I wanted to have it always with you to be filed the same pages in my portfolio. It took a lot of strength to the always up to 3 pages holes durchzuhauen it was only a matter of time until the thing of the mind gives up - today 09/16/2013 it was because as far. It has bent and no longer punches all 4 holes - now I buy a correct punch remains then in desk. The collection container is also a joke because the ausgestampfte paper can not be run from the Behäter and if you have the Andeckung removed Schwerigkeiten it reattached
