The Omron M6 Comfort likes to make its readings comfortable. The preformed cuff sits easy around your arm and fits snugly, making the reading a lot more reliable than when done with a standard cuff. Aside from this, the Omron M6 Comfort will also make sure everything goes smoothly during the reading. It will warn you when you move to much, or when an irregular heartbeat is detected. The measurements for two different users can be stored in the Omron M6 Comfort's storage.
