Five to seven day battery life

Questions about this item

Will the 2.5 mm thick ring sit comfortably next to my existing wedding band?

At just 2.5 mm thick the ring is designed to sit flush alongside other bands without catching or adding bulk.

How can I verify the heart-rate and blood-oxygen readings are accurate after I start wearing it?

Open the companion app after a few minutes of wear; live heart-rate, SpO₂ and HRV graphs should appear and update continuously.

Does the package include a sizing kit or do I need to buy one separately?

The box contains the smart ring, a 300 mAh charging case and a USB cable; a separate sizing kit is not included.
