It is very well built, punches things 4mm thick, has a deep throat, has markings for vertical and horizontal alignment, great grips, a lock to keep it closed, and is super easy to punch through chipboard!

This thing really works.

I love this thing!

This thing is super amazing.

This thing punches through all kinds of materials, including laminated pages.

This thing doesn't work AT ALL

This thing punched through with no issues with a clean cut

I can't say enough good things about it.

I wish more things were made this well.

This thing is sturdy and does a great job

This thing is fantastic

This is best thing I have found for punching holes in thin metal.

These things work great

It will punch through most things
