    Even better than expected. Helps monitor daily activity and health. Some information is not available until several days or weeks data has been collected. I found the sleep pattern, heart rate, and oxygen saturation very interesting. You can “tag” various activities during your day, and it shows you how each activity affects your body. Fit is very important. Get the sizing kit before purchasing the ring. The kit says to wear the sizing ring for 24 hours. I recommend at least 2 days. My fingers change size depending on temperature and activity.
