I’m very pleased with the quality as well as the price and I’d definitely recommend this smart ring. I waited a month of use so that I could give you a honest review. I bought it primarily because of the Glucose Monitor functionality so I could monitor my glucose levels. I’m not diabetic but like to track my vitals during pre/post meals as well as workouts. It automatically tracks all the vitals every few minutes plus you can get instant results by pushing the button for the readings you want.

Store owner replied: Hello, you can contact our customer service for handling.
This ring works well. It isn’t right one but it is close enough, I feel, that you could catch trouble coming. I did notice, especially when my hands were cold, the fit was loose, and I think this could be the reason for the slight difference. Or maybe what I was checking it against was awry. But I shall find out soon as I just ordered another, in one size smaller so the fit should be more consistent. Standby for the next review!

The smart ring works great It looks real nice is accurate except for the glucose reading its not to far off but enough to cause issues with blood sugar It still helps me to get a general idea of where my sugars are at. The other measurments like heart rate blood oxygen sleep blood pressure and temp are all very accurate Its got great battery life a charge lasts 3 to 4 days and charges up very quick Its a very good smart ring for the price and i recommend it to anyone looking for a good smart ring at a very good price

The ring was quite hard to get calibrated for the glucose reading but it seems to work very well after that.

FITAOS R08 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
It works well for what I want. Suggest improvements. Glucose readings appear to follow a preset daily rhythm hard to keep to calibration. To get ECG to work well, the ring needs to press against a body part. Grasping hands together tightly with the ring will also work close to the cellphone app.

Todd H. 5/5 Verified
FITAOS R08 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
I love that it’s blood pressure & blood glucose measurements can be calibrated to an independent standard. Also, I haven’t seen such a broad suite of measurement types in such a small package. Lastly, a single charge lasts over a week. The colors in the HealthWear app’s blood pressure display need greater contrast (orange & yellow are too similar). I have a hard time reading that display. Everything else I really like and find very useful… its a well designed app.

I love all of its capabilities. But that said, the ECG function sometimes doesn’t work if you have dry skin.

The ring seems to work correctly after it is calibrated. However, I can't wear it because it is so large. I tried measuring my finger when I ordered the ring but the size I thought I needed would fit a gorilla. I never wear it because it is just too big.

I am loving this smart ring. I have recommended it to some family and coworkers because it is so great. It has helped me monitor my blood sugar and blood pressure throughout the day. My primary reason for buying it was for the blood glucose monitoring. I highly recommend this product.

It's a lot smaller than it's should be. Had to order 2 and the second one is still too small even though I followed the instructions on how to measure for the proper size.

Charge lasts for ~ 5 days and fully recharges in ~ 1 hr. I'm still getting used to how it tracks different metrics as its different from my fitbit, but it integrates with apple health which is a plus.

Readings are off by 5%. If you can make the app updates to get readings every 5 minutes instead of 30 minutes will more accurate averages Otherwise so far it looks good.
Rajesh P. 4/5 Verified
FITAOS R08 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
Once calibrated with an actual blood test the glucose monitor is pretty accurate. I wish it had more exercise routines to capture like swimming, driving. ECG has some trouble to capture, but provides very useful insights when it does work. Price is a great advantage without any need for subscriptions.

It would be great to put heart conditions already known so you can monitor any extra changes. And i have orthostatic hypotension automic dysfunction. It always say good keep it up but it drops 20 to30 points and still said good job but i had to go to the hospital because i felt horrible and passed out :( but if we could fix that it would make a huge difference in my life
