[Size First Before You Buy] This smart ring features a wider and thicker ergonomic profile for sensor performance. For optimal comfort, utilize 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 ring weighs around 3g. Owing to its smart sensor design, it may feel distinct from a regular ring initially. Most users adjust within a few days of wear for daily activities and sleep. [No Subscription Fee] The ring offers access to sleep, heart rate, activity, SpO, and stress trends without any app subscription fees. It is intended to support daily wellness awareness, not to substitute medical or professional devices. Your health data stays accessible without recurring payments. [Battery Life & App Connection] The battery can last up to 7 days depending on usage and settings. The ring syncs data periodically via Bluetooth to optimize power consumption and may disconnect when idle. Charging duration and battery performance may differ based on usage habits. [Water Resistant & Everyday Use] With IP68 water resistance, 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. [HSA/FSA Eligible Smart Ring] This HSA and FSA eligible smart ring permits qualified customers to use HSA or FSA funds for purchase. Featuring advanced health tracking, sleep monitoring, activity tracking, and wellness insights, it is an excellent smart wearable for men and women.
