This paper punch does a good job of punching holes in the stack of papers. I only wish that it had a useful side edge paper guide so that the punched holes between individual stacks of paper align with one another. This would be a significant improvement.
This light-duty paper punch is good if you use 20 lb paper normally but ever since I switched to thick 28 lb paper I've had trouble punching any more than 6 or 7 sheets. That aside it's good for regular sized documents and it hasn't jammed up on me when I use it properly.
