Overall this is the best stapler we have had in our warehouse office. It staples large bundles better than anything else we have tried. It only has one flaw which keeps me from rating a 5 star. The tab that you pinch to release the spring where you load the staples has a tendency to break. I ordered three of these and two have already broken. My guys like this stapler so much, that they tape the ends so they can keep using the stapler. I do plan on letting Stanley products know about this issue and see if they can make it stronger.
