We no longer purchase the Swingline brand staplers. They used-to be the standard, but that is no longer the case. Swingline seems to be using very low quality parts. Their expensive heavy duty staplers only last about a year, sometimes less! This is what we started buying to replace all our Swingline staplers. This one has a lot of power. We haven't had any problems with ours and have purchased four of them so far.
