Who is it ideal for?
Based on its spec sheet, it fits people who want very discreet health and sleep monitoring, without wearing anything on their wrist or paying a subscription for basic features.
Who is it NOT the best option for?
If you want to see notifications or data on the device itself without checking your phone, a screenless ring isn't the right format — a fitness band or smartwatch would be a better fit.
