The problem is that the top guide is too big and doesn't line up with the bottom cut so it doesn't even come close to passing the punch. The top acrylic had to be drilled out and then leveled. Unfortunately there aren't any and they are too big. This makes it impossible to get a decent cut from even thin plastic (.030 gauge) and results in blunt hits after the first cut, no matter how soft the material. It could be a lot better.
