1 FITAOS R09 Smart Ring
1. I have been using my Smart Ring for 3 weeks. 2. The APP was bit difficult to pair but once you understand the startup with Bluetooth recognition before using the Fitaos App...then all worked just fine. 3. I bought the FITAOS R09 Smart Ring and have found the Uric Acid indicator to be inaccurate. 4. Notwithstanding the above points all the other body health indicators worked reasonable well for a non-medical device.
