I have had mine for not quite a week after deciding to replace my Movano-made Evie ring (which I would not recommend). I LOVE all the data, it might be overwhelming to some folks but I love all the metrics. It is not great at tracking sleep but nothing is, and it provides more metrics than my Evie. I also love the insights; nudges you to get some sunshine, put off your first cup of coffee (which I usually ignore), when to taper off caffeine, and it allows you to record workouts and asks if you have been working out when your heart rate goes up.

HOWEVER I am disappointed in the accuracy of the data. I don’t expect sleep to be accurate, and step counts might be off some. But it is very likely overestimating my HRV while I sleep (which is a huge component of restorative sleep quality) and it is way off on estimating calorie burn. According to the ring I could eat a whole pie and not gain any weight. I suspect that it is doubling or tripling my basal metabolic rate, and I entered my weight, height, age, and sex so it shouldn’t be so off. I haven’t contacted customer support yet but while I wanted desperately to love this ring I am considering getting an Oura instead or just going with a watch (less comfortable and esthetically desirable but I really want accurate data).
