I like the fact that this stapler will staple so many sheets without using a heavy-duty stapler. Most times it staples fine but very often my staple crinkles on one side--always the same side so I have to pull that staple out and re-staple. This happens too often. Also my stapler does not repeat "does not" take an entire strip of staples even though that is described in the specifications. I am using the suggested Optima staples so I'm not sure why any of this is happening. I may attempt to return it or replace it with the same model soon. I really like that it staples so many sheets so that is why I'd like this same stapler but working properly.
