The first test was good. Twenty copies of the report should be filed in folders. It was over 180 pages. We stuck to punching 20 pages at a time. With the guide on the side, the pages line up nicely. We also took care to remove the perforated 'chads' that were visible from her translucent closed 'basket'. Easy to use, very intuitive. Good two year warranty and price for the number of pages that can be punched at once. Nice results.
