This is the best Manual Staple Gun I have ever used.  I got tired of the run of the mill manual staple gun.  The low tollerances in manufacturing lead to too many jams and poor performance.  This staple gun is priced right and has close tolerances so no more staple jambs or poor performance driving staples.
