It didn't do what I thought it would
Unless I'm not doing it correctly, this was useless. When I put it in my machine there were spaces on either side of it and my papers slid down into those spaces as if I was not using this at all. I really liked the idea of having the holes punched closer to the edge of the paper, but I could not make this happen.
I would give this zero stars, but I could not submit this unless I gave it a star rating.
