I use a 3 hole punch every day for work. I had one that was very easy to slide the paper into although only 6 or so at a time. I wore that punch out a side rivet broke on the handle. I thought I was buying the exact same punch. On this one guides are not level with the base so you have to fiddle with the paper a bit to get it aligned. This takes time...more time than I care to spend in the company of a 3 hole punch.
Bought this when I had to work from home for a long period. This is ok for a few sheets of paper. Doesn’t line up well and can’t do more than a few sheets at a time. Would not recommend.
