Customers are saying

Customers are pleased with the overall performance, phenomenal sleep tracking, and the comfortable, sleek design of this ring. Users also appreciate the long-lasting battery life and the durable, scratch-resistant finish. While most find the device easy to wear, some individuals noted that it takes a little time to adjust to the size and slight weight on their fingers.

    largely positive, highlighting its ability to turn biometric data (sleep, HRV, temp) into conversational, actionable health advice, helping users understand patterns, manage stress, adjust schedules (like jet lag), and even spot early illness, though some users find it basic or wish for deeper functions like meal planning, making it a powerful, personalized wellness coach.

    A good health monitor, probably the best one on the market right now although a number of new devices are coming online. Purchase has a gift for my wife who really liked the style and the fit. I’ve now had four of these rings myself in various generations and finishes. Found them useful, although the battery life does decline with age.

    I’ve had my ring for about 3 weeks now and I am loving it. It’s still getting use to some of my habits but for the most part it’s been tracking great! I love that it senses your body needs rest or that it’s fighting something and is so accurate on sleep etc. I’m hoping this will help me with my health in 2026! I would definitely buy again!
