3 Of Ways Stapler Staple Gun Heavy Duty Chrome U-Shape Nails Stapler Nailer

Parts missing (circlip on one of the handle pivot pins). Does NOT work upside down. Double feed staples constantly. For every one successful staple I lost approximately 3 others and the time it took to pull the double fed staples out of the gun. Then it suddenly just jammed and is now totally stuck and unusable. This all in the space of 30 mins. Low quality. If I could I would have given 0 stars
