Smart Ring with Call/Clock/Events Alerts, No APP Subscription, Body Temp/Heart Rate/Women's Health Tracker, 5ATM Waterproof Fitness Ring for Android & iOS (Silver,11#)

UPDATE (1/20/2026): In an amazing show of "ensuring customer satisfaction", a member of customer service reached out with recommendations to help resolve the issues I was seeing. I'd already ordered a smaller size ring (size 7) and after Amazon horribly delayed my delivery, I finally received it... and it fits perfectly!! As per my hypothesis below (also confirmed by the representative), the smaller size ring not only fits better on my finger, but the vibrations are wayyyyy better - actually at the point I was expecting!! I've not missed any messages, calls, or alarms yet! The app is pretty neat too -- not only can I take on demand heatrates, but I can take my temperature and O2Sats on demand as well - pretty nice. I've only worn this ring one night, but the sleep data appears to be more detailed than that of my Oura. So far, I'm LOVING this ring and I've updated my rating accordingly for both the ring and customer service. :) Thanks again for your help, customer service! ORIGINAL: I have an Oura (which I absolutely LOVE) but my Oura doesn't have vibration functions and since I no longer wear my watch, I wanted something quick and easy that would vibrate to alert me of message, calls, etc -- in comes this ring. Firstly, I really like how this ring looks. Nice form, not as thick/bulky as my current ring and just pretty modern/streamlined in general. Secondly, I think this ring runs big. I purchased a size 8 because that is the size I needed for the finger I plan to wear this on and it's pretty much falling off. I wear a 9 in Oura and I can actually fit this ring securely on the Oura finger with no issue. So the size 8 here fits more like a 9 (in my experience). Lastly, vibration wise, it's hit and miss. For me the vibrations are super low (not enough to alarme of I'm not waiting for it) and even in instances where I set reminders/alarms to test the vibration function, the ring did not consistently vibrate. I was thinking that maybe a better fit would allow for better vibrations so I used it on my Oura finger since it fits perfectly there -- the vibrations seemed a bit stronger but not by much. Maybe I'm expecting too strong of a vibration ?

I’ve had this 3 months, don’t use the phone notifications, and the battery only lasts 1 day. Not worth it.

Update: 2/27/2026 Its been almost 2 weeks now and I really like this ring! I've had to charge it twice. Once when it arrived and again 7 days later! All the metrics are working correctly. The light vibration is there and I've gotten use to recognizing it now. It is very light but perfect to where it doesn't startle me at all. The body temp, sleep record, HR, O2 all are correct! The free application is user friendly, so easy. The measurements are easily changed between metric and imperial. The record keeping/history to compare is great. I've had other smart rings but none of the previouse rings kept a good record for review. The AI Health report is helping me see my improvements and my areas that need to be improved. I'm very happy with this purchase! This just delivered (2/15/2026) and paired quickly after being fully charged. I'm impressed and looking forward to see how well the application and the ring work together in the metrics. More to come.

Xiaobi Smart Ring..what I like the most is the notifications of a text or call on the ring. It slightly vibrates, which on most occasions does alert me. I had to contact the seller regarding the 1st ring I was sent. About 35 days of having it, the battery was draining over a period of 2 hours or less. They did send me a replacement and currently this ring has been working great. The step count runs higher than my Samsung watch does, sleep tracking is about the same, heart and oxygen rates are somewhat close, but, I really bought the ring for the notifications. I only gave it 4 stars due to the 1st ring, and not having the replacement ring long enough to know how long it will last. Update 11/16/25: ring is dead again. I believe this must happen with all smart rings

I’m super disappointed with this ring! I bought this to track my temperature and I loved it for the first two weeks. It was light, easy to wear you can turn off the notifications (I wear a watch), and I loved that you can get measurements on demand. I also have a new born so tracking my sleep was very helpful. HOWEVER, I am so disappointed with the battery life. At first I thought it was just the ring itself but not I think the connection to the charging case doesn’t work at all. The battery drained in less that 12 hours! Not helpful when you’re trying to track sleep and go about your day. I really wish this was better
