[Size First Before You Buy] The Smart Ring features a wider and thicker ergonomic profile for sensor performance. For optimal comfort, use the sizing kit before ordering. If you are between two sizes, we strongly advise selecting the larger size. [Titanium Build] Made from durable titanium alloy, the Smart Ring weighs around 3g. Owing to its smart sensor design, it may feel different from a regular ring initially. Most users adjust within a few days of wear for daily activities and sleep.

Charging time and battery performance can vary based on usage habits.

For comfort and skin care, we suggest removing the ring periodically, especially during extended wear.
