First punch was great! After that I had to manually press the punch through the paper by manipulating the paper itself. Not sure if the alignment got messed up after the first punch? Either way weird.
It punches holes. I only need to do a sheet or two at a time and it works fine. Just be sure to place the paper in the correct spot under the angled tab. I like the little catcher for the holes so they don't go all over the place.
