[Choose Size & Charge the Ring Before Buy & Using It] Before purchasing our NEXUS smart ring, we strongly recommend that you refer to the size chart and carefully measure the circumference of your finger. This will ensure you get the most comfortable wearing experience and easily avoid any discomfort from an ill-fitting ring. And please fully charge when you receive the smart ring, so that it can work normally. When wearing it, keep the optical sensor in close contact with the skin of your fingertips to ensure accurate data. Also, remove the smart ring before touching slippery objects on your hand to prevent it from falling off.
