I'm generally pleased with this wire binding machine. It does a nice job, and the binding looks good and professional. About the only real problem with it is that the hole punching can't handle a lot of pages - particularly with thick paper - and it's a bit more of a manual, two-stage process than I thought it would be. You punch the pages, then take them out, then line up the wire, then put the paper into the binding, then carefully pick the whole thing up and put it into the binding machine and press it, then trim off the excess. I was thinking, punch, thread in binding and done.
But at the end of the day, it was cheaper than I was expecting and it really does do a nice classy job. I'm pleased.
