Customer Reviews
I love the ring! It's an easy way to track daily steps and watching vitals!! Only issue I have is the ring re-styncing after I charge it. There seems to be a lag between the devices that can last awhile, then it's fine again

I love the ring, it’s just a little too small for the finger I wanted to put it on.

Like the ring I have had it for a while the only problem I see is the finish doesn't stay long mine is almost all silver now. I'm thinking mine is R08

FITAOS R09 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
I like all of the things it can do. Other than sometimes having trouble getting the EKG function to work, it works perfectly. Has a long battery life and is accurate compared to some of my other devices that I use… Apple Watch, Hume Health Band and for the cost it tracks reasonably to my CGM too!

FITAOS R09 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
I purchased two rings; a size 8 and size 11. The size 8 is great, the battery last few days but the size 11 battery is not that good. The size 11 must be recharge every day.

Blood glucose is very close to my normal Glucose monitoring system. I a guessing that it reads capillaries.

FITAOS R09 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
Needs charging every 4.5 days and charger sometimes doesn't work. It cannot get wet as per watch instructions that came with it?? So I have to take off to wash my hands and risk of loss is great. Blook pressure rating is LOW and incorrect. ECG blood pressure is more accurate it is a tool and will check accuracy of blood glucose when I do my blood work with doctor I do like the look of it.

Store owner replied: Hello, you can wash your hands while wearing it. The ring is waterproof.
Water resistance works fine. I have used it while washing hands and swimming in shallow water without problems.

It takes a bit of time to get used to interpreting the data, but once you do, it is actually quite useful.

FITAOS R09 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
I got the ring as a gift for my mother and she has really liked it. It does give comparable readings that she can check the standard way and she has gotten to where she uses the standard way less often and depends more on the ring readings.

FITAOS R09 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
The ring works as expected. I've been using wearables for a few years now, primarily watches. I also have the old-fashioned and automated monitoring devices, and I will occasionally bounce the results off each other for comparison. There is a marked difference at times, but the data is usable. The one thing I found interesting is that when I received the ring(s), the corresponding emails and instructions were in Chinese. This didn't affect the operability, just getting everything started.

FITAOS R09 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
Have been impressed with the capabilities of this product, thus far. It has been approximately 6 weeks since my purchase. HR, BP reading have been comparable to other instruments, plus the O2, Sleep Mode, HV readings have been informative. The EKG readings, have at times, dropped off and failed to read accurately., however when successful they too have been compared to other instruments offering this task. I would recommend this very economical price product for anyone who needs regular similar health readings without the bulk of a smartwatch!

I reference the data everyday. It gives a good general picture of how my heart is and if I need to recheck with a more reliable instrument

Good for general wellness tracking, but not something I would rely on for medical-level accuracy.

I like that it does not distract me like a smartwatch with notifications. It is more focused on health tracking.

I love the Ring; However, I should have ordered one or two sizes larger, fits too tight.
James A. 5/5 Verified
FITAOS R09 Blood Glucose ECG/EKG Blood Pressure Monitoring AI Health Analysis Smart Ring
I love how my ring measures my blood pressure every hour and keeps track of all my readings. Recently my doctor had me wear a 24 hour BP cuff and I hated it so much that it spiked my BP and they prescribed medicine that could damage my healthy diet, kidneys and skin. I know that my ring doesn't replace my doctor's advice but really, I chose the ring over the meds and can check with my home BP cuff at any time.

I love this smart ring, much better than the smartwatch I had. It's not 100% accurate, but close enough to provide me a baseline without the need to prick myself with a needle every day. I wish the battery life was longer. I am confident that your next version of this ring will be perfect. Thank you, Aneta Montgomery.

I have worn the ring for 3 days now. It took a bit to get used to wearing a bulky ring, but I think I am there. I am really impressed with the vitals readings. The BP reads high, but it is consistent.

I also appreciate that there is no subscription fee huge bonus! It is comfortable to wear all day and night, even while showering, thanks to the IP68 waterproof rating. It is the perfect combo of fashion and function.
