If you're a baby boomer you've encountered this staple gun somewhere along the way.  Reliable, heavy duty, and does the job.  Sure, there are refined versions of this stapler out there from different manufacturers, but the fact is this gun gets the job done at the lowest cost, given those competitors.  Would I want to use this all day?  Nope.  It takes a strong pull to bang that staple home.  But for the price --- and reliability --- it can't be beat.
