Works fine for single thickness paper but if you try to do more than 1 at a time it's a little difficult. But all in all does what it is supposed to do!
We got this hole punch and without testing it out I put it on the desk of one of our teachers. When I borrowed it from her later I noticed that the punch was offset and did not fit well enough to close rendering it useless. By that point we had already had it for a while and it was so cheap it wasn't worth the return.
I used these to hole punch some paper. I should of limited the amount of paper but I didn't and ended up bending the hole punch causing it to break. I would recommend these if you were only punching holes in a couple of sheets of paper rather than a stack.
