Query: Using it takes patience

This stapler jammed EACH AND EVERY TIME I used it. In other words, after using its stapler once, I had to eject its stapler holder, push it back in, staple one more, eject, push, staple.....I am not sure the problem originated from bad design and/or manufacturing, but I am sure I will never purchase it!
