Used to punch holes in invitations for wedding so only needed for about 300 punches. Relatively comfortable for an inexpensive punch [$]. Did the job great. I can imagine it's not the best for heavy usage but it works well for occasional use.
If the punch was used with two or three sheets of paper it worked fine however with a single sheet of paper the punch would leave part of the punch out still hanging there. It was then nessisary to remove the little circle by hand.
I was looking for a hole punch when I came across this magnificent piece of equipment. It punches through standard printer paper like a hot knife through butter. Highly recommended for your hole punching needs.
