[Size First Before You Buy] The Smart Ring has a wider and thicker ergonomic shape designed for optimal sensor performance. For the best fit and comfort, we advise using the sizing kit before ordering. If you are between two sizes, we strongly recommend selecting the larger one. [Titanium Build] Made from durable titanium alloy, the ring weighs around 3 grams. Its smart sensor design may feel different from a traditional ring at first. Most users get used to it within a few days of regular wear for daily activities and sleep tracking.

Charging time and battery performance can vary based on individual usage habits. [Water Resistant & Everyday Use] With an IP68 water resistance rating, the ring is suitable for daily activities such as hand washing, workouts, and light water exposure. For comfort and skin care, we suggest removing the ring periodically, especially during extended wear.
