Query: Not impressed. OK - I was disappointed

All I can say is that I expected a lot more from Swingline. This stapler is marginal at best, in terms of both its construction, and performance. It continually jams, and this is just for light duty, such as stapling 3-4 pages. I expected more from Swingline. I've used ACCO / Swingline products in the past, with much better results. This stapler does not compare to the Swingline staplers made 15-20 years ago. Go with the metal versions, or try to pick up an older one at a flea market or a garage sale. You'll get better results than with this model. IMO.
