Adjustable lever for different size papers, Allowing for symmetrical organization even if the holes were punched at different times. Satisfied. Does the job and does it well.
Forklifts:
If You Want to staple more than a few pieces of paper together dream on. Even up to about 8 pages is impossible, Which renders it almost useless. I had to staple a few pages at a time, align the holes and remove the staples before I could staple a larger set of documents together. We're talking about fewer than 15 pages here. TOTALLY USELESS AND NOT WORTH THE MONEY. Get a heavy duty stapler instead if you intend to staple more than 8 pages together.
