Wearing Your QRNT
The ring should fit securely and comfortably around the base of the finger of your choice with the sensor resting against the palm side. QRNT is water resistant, so it can be worn during showers or shallow swims.
Due to the sensor inside each ring, QRNT fits slightly smaller than a standard ring. If between sizes, we recommend sizing up.
