4.5 ⭐ Excellent customer service. Not 100% accurate but works.
mermaidx7—September 4, 2025
Runs small, I'm not able to wear it on the fingers I had planned, but they replaced it at the same price. Measurements are not matching my galaxy watch, blood pressure cuff and O2 monitor. BP top number is always too low but bottom number is close. Sleep doesn't record during daytime hours. Nor does it match my watch data. Heart rate, sleep and steps are automatically recorded. For BP, O2, HRV, and Stress - open the app and push a button individually. I really like the app. Looks great and easy to read. If close but not accurate works for you then buy it. However if you need really accurate measurements, I wouldn't recommend. Battery lasts several days, perhaps 4 ish. I'm quite sure the ring I got was already used but it was really a low price, so for now I'm using it as it works fine. Read more

Sleep monitoring
JoAnne Hortman—January 15, 2026
I was hesitant at first when I read reviews about the battery charging. Mine has lasted 2 days plus charges quickly. I use it to monitor my sleep. Liked it so much I bought one for my daughter and husband. Read more

Not accurate
Lisa P.—September 8, 2025
Not very accurate. Never matched up to readings from BP machine or when I'd do a fobs. Sending it back. Ring was nicely made and pretty but doesn't work how I needed it to. Read more

This tells me more than my Fitbit watch does. Battery doesn’t last long though. Seems I have to charge it every 2-3 days. Read more

Powerful health assessment tool
Renee—October 25, 2025
The ring is beautiful and works well! It took me a minute to get it linked to the app but since it’s established I have had zero problems. It’s waterproof, long battery life and easy to charge. The heart rate, blood pressure, HRV, sleep and work out monitoring is excellent and accurate. I see no future problems for durability as it’s well crafted. REVIEW UPDATE: no longer charging and lost stones. Doesn’t track sleep anymore and the battery dies quickly Read more
