The Oxo rolling mincer is lacking one important feature: Blades! It has thin little discs of metal, but they aren't blades. They are dull, dull, dull and do nothing but mash your herbs to pieces. Do you really want finely hammered herbs? It's like replacing a chef knife with a screwdriver. Ok, it's missing a couple more features: It's too small and the "blades" don't rotate independently. After the first use I noticed one of the "blades" had already bent about 5-10 degrees from parallel (which would have been prevented with independent blades). For quantity tasks, it is far slower than a chef knife. Try a nice double- or triple-bladed Mezzaluna instead. Mezzalunas have real blades that can be re-sharpened. (But don't buy one with a matching bowl shaped cutting board, they completely ruin the rocking action of the Mezzaluna).
