Have had one for the past 5 years-found it in a box of kitchen stuff left when my stepdad passed away- and only today found out what it was. So glad I kept it! I ran out to my herb garden and picked a bunch of oregano. I took the leaves off the stems. It worked wonderfully. The result was nice evenly minced pieces. I can't wait to try the others. I suspect it won't work too well on larger leaf herbs like basil, but should work great on the more "woody" ones. I also didn't overload the cup. By now I'm sure you tried it and hope you were successful. But if not, give it a try.
