[Size First Before You Buy] The Smart Ring features a wider and thicker ergonomic profile designed for optimal sensor performance. For the best comfort, we recommend using the sizing kit before ordering. If you are between two sizes, we strongly suggest selecting the larger one. [Titanium Build] Made from durable titanium alloy, the ring weighs around 3 grams. Due to its smart sensor design, it may initially feel different from a regular ring. Most users adapt within a few days of wear for daily activities and sleep. [No Subscription Fee] This Smart Ring provides access to sleep, heart rate, activity, SpO, and stress trend data without any app subscription fees. It is designed to support daily wellness awareness and is not intended to replace medical or professional devices. Your health data remains accessible without recurring payments. [Battery & App Connection] The battery provides up to 7 days of use depending on usage and settings. The ring syncs data periodically via Bluetooth to optimize power consumption and may disconnect when idle. Charging time and battery performance may vary based on 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 recommend removing the ring periodically, especially during extended wear. [HSA/FSA Eligible] This HSA and FSA eligible smart ring allows qualified customers to use HSA or FSA funds for purchase. It features advanced health tracking, sleep monitoring, activity tracking, and wellness insights, making it an ideal wearable for men and women.
