Great entry level fitness tracking ring
I've had the ring for almost a week and so far so good! I like that it doesn’t scream fitness tracker! I bought the smallest size they have and it is a bit cold so it twirls on my finger. However when I warm up it stays in place just fine. I'm taking off one star because the app interface is lacking. It doesn’t update my information in real-time. I have to click on my steps, then sleep, and so-on before my data will update. And it never shows me accurate battery status. I'm still showing 53% rven after a full charge.

Nice ring
Ring gives good fitness information. Charges quickly and remains charged for 5 days. It fits a little large and it fell off my finger once. Would recommend to others with a better fit.
