I've been using this 2 hole punch for a few months now. I would say that on average I edit about a ream of paper a day. If you keep the tray empty and don't try to do too much at once, this machine works great. I regularly punch over 15 sheets at a time and it hasn't stuck with me yet. It definitely sounds like it's harder to work with a thick stack of paper, but it always gets the job done. It's such an improvement over the manual puncher I used.
