I am delighted with this cutter. My main use is cutting the binding off of books for use in a sheet-feed scanner. For this task, this cutter is outstanding, especially relative to the cost. If you set it up well, set your alignment fence right, clamp the paper in place, the leverage and sharpness of the cutting arm is incredible. On one smaller book I actually kept pressing, not realizing the book had been cut. I hardly felt the resistance. I regularly cut books that are .75-1.0 inches thick with no problems at all. I can't yet comment on durability, but the cutter feels very heavy and solid, everything handles firmly and it feels very sturdy. If you want to cut thick stacks, this is a great cutter for that.
