Finger size can change during the day, so try your sizing kit at different times. If your ring fits well, you’ll get more accurate sleep tracking and heart rate data. Users say that a good fit makes the ring so comfortable, you might forget you have it on. But if the fit is off, you could see spotty data or even want to return the ring.

Common reasons for returns include poor sizing, missing health data, or discomfort. Some people even switch fingers to get better results. Always check the return policy before you buy, just in case you need a different size.

Note: The right fit means better comfort, more accurate health insights, and the best for sleep tracking.
