Sizing, battery, shipping, and what Rstsoe is — and isn’t.
How do I choose my size?
US sizes 7–12. Toward the end of the day, measure the finger you will wear (inner circumference or diameter) and match a standard jeweler’s ring chart. If you are between sizes, size up for comfort. Final size is selected on Amazon at checkout.
How long does the battery last?
Is it waterproof?
Is there a subscription?
Is this a medical device?
What’s in the box — and how do orders work?
