The M221 redefines ‘quiet as a mouse’. Experience the same click feel as a standard mouse but with almost no click sound. Feet made of high performance material and a rubber scroll wheel help to minimize distractions and maximize productivity for you and those around you. The M220 allows your family to keep right on sleeping and your officemates to keep right on working. With its compact, ambidextrous design, you’ll be a silent hero everywhere you go.
