I just received this in the mail today; so naturally I started testing it out ASAP. Since I've never used a punch before, I tested it out on a paper stack cover that I thought was less than attractive. I'm happy to see that it turned a less than stellar design into something I can absolutely work with.
I've done some math on what I'd spend on photo corners in this quantity, and am pretty sure this will pay for itself with another round of page punching.
My husband, however, would be happier if it came with a means to make smaller corners as well; but I'm still happy.
This punch is one I will use over and over. The photo corners are a little larger than what I expected, but I think I actually will use them more frequently than I would have used smaller photo corners. Very practical purchase---I'll definitely get my money's worth out of this punch!
