Love this smart ring

This ring is fantastic especially for the price it's at. I wear a Garmin Venu 3s and the smart ring is matching my watch readings. It vibrates when you get a call too. There's an alarm vibration setting but I didn't need that so didn't use it. I highly recommend. Read more

Smart Ring

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 Read more

Very pleased!

So pleased with this ring. I searched high and low for a ring with on board alerts. None of the mainstream, $400 rings offer this. Somehow, this $50, off brand ring has this feature. Gently vibrates for calls, texts and alarms. I wore it with my Google pixel watch for 2 days and nights and the stats were spot on compared to the watch. Read more

Does not work as advertised

Ordered based on the vibration feature. When it works, this is great. However, the ring disconnects from the app often. The only way to reconnect is to put in charging box. Would never record sleep, eventhough I wore it 24 hours. Does not record your steps unless you start the clock. Still didn't track steps. Wish it worked better. Will be returning. Read more

Great product

I am not one to write reviews, but this was a pleasant surprise product. I am not a fitness junkee so workout tracking is need but not high priority. I needed a ring to keep charge, alert me of calls, and monitor my health. This is the perfect ring for me. Read more

Nice ring, low vibration

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 ? Read more

Lots of features, no subscription, room for improvement

1/11/26 Dropped to two stars. After only a few months, the batter life is terrible, doesn’t even last a whole day. I feel like the app changed as well and used to have a stress level measure, but now it’s not there. Still like the unique vibration feature, but sometimes it randomly vibrates. So far so good! This ring is really unique with its notification feature. I really hope they add the SMS notification feature, it’s already on the app, but I am seeing in the description it’s not yet available. The app is a little laggy and has some bugs, thus the one less star. The ring is heavy weight, so I need to move it to different fingers throughout the day, but this does not seem to have impacted the data it tracks. For the price and lack of subscription needed, this feels like really great value for the money and features. Read more
