This stapler would only work correctly half of the time for me if that. I can't tell you how many documents I messed up trying to get them out of the staple still stuck to the stapler. I would NOT recommend this and frankly would tell people to avoid this product. I'm very disappointed.
As a teacher I use this to staple together all of my students' work into a book. I have 25 students so I was looking for a product that could handle the job & use regular staples so I wouldn't have to buy special staples! This delivers!
This is an excellent stapler we have 2 in our office. It is powerful and does staple up to 30 sheets easily. It staples flat. However for some reason after a lot of use it tends to jam. I then have to pull out a lot of bad staples in the paper. But after pressing the stapler down about 3 times to clear staples out it is ready for use again. It is possible that the jamming has something to do with the humidity (moisture) of the paper but I'm not certain. Just make sure you have a backup for the days that it decides to jam.
This is actually the best stapler I have ever owned for my desk or at home its perfect. It handles bulky or lots of pages at once. It has some real power going through padded envelopes with ease but lightweight and doesnt take up much space. Its perfect for the copy room but you may have to put it on a cable tie-down....I promise you other people will try to steal it.
This little stapler works like a charm. From just a few sheets and up it works without jamming and the staples are not mangled ever. It even works great when hand-held which my older stapler of the 'known brand name' did not - that one could never work other than when flat on a desk. Being a "flat" staple product big stacks of stapled documents do not "roll up" in the stapled corner!
