Size and appearance are correct. But the ring measurements are questionable at minimum. All 4 stats are not accurate. I am wearing my Garmin Forerunner in parallel, and steps on the ring are reported 50% higher by day, Heart rates are too low and remain nearly static, Sleep time is off by 1h +/-. Blood pressure a flat line over 20 measurements (and I am not that fit). I will return as this device is delivering false positive stats.

works great

This ring is fairly nice. It does scratch easily. I like that it's not screaming in everyone's face that I'm tracking steps. It does a comparable job of tracking steps when compared to my fitbit during exercise. During daily activities, the ring measures fewer steps than a fitbit (I have a charge 6). The app measures blood pressure, heart rate, sleep and SpO2. I can say that, except for blood pressure, the measurements seem accurate. The BP readings are what I would expect but I can't say for certain they're accurate. The app tracks workouts but it seems that it needs to be open the entire workout or it will just stop recording. Sometimes it records 30 minutes, sometimes 2 minutes. When the app is on the screen it records well. I have an android and my wife has an IPhone, we both have a ring and the app stops on both phones when trying to record a workout and the app is running in the background. Sleep cycles/duration seem accurate on the app. Update: heart rate during exercise is off. I've tried several fingers and the ring will read 89bpm while I'm doing HIIT and my fitbit measures 150

SpO2 reading is far too optimistic. I have CHF and track my SpO2 regularly with several finger tip devices. This ring consistently reports SpO2 to be <>98% which I know is incorrect.

I’ve worn the ring for three days now and comparing steps with my fitbit… not even close to accurate. BP, o2 levels and sleep are very close, but for steps not so much. I’ll try for a while longer but if it can’t accurately measure steps it will be returned.
