Great ring!
Great ring! Size fits very well. This was very easy to pair and bind. App is easy to use and understand. It is magnetic so when you charge it the magnetic will click. Comes with a charging cord. And a couple ring cases if you want to change the color.

Three Complaints and Three Stars
Three ComplaintsSizing Issues:I purchased the sizing kit before ordering my ring, and according to that, I was a size 11. However, when the size 11 ring arrived, it literally fell off my finger. Interestingly, the ring packaging included another sizer, which showed I was actually a size 9. I returned the 11 and exchanged it for a 9, but the 9 feels a bit tighter than I’d like—so now I’m considering trying a size 10. The sizing process definitely needs improvement or more consistency.Phone Alert Functionality:One of the main reasons I purchased this ring was for phone call alerts, since I have to keep my phone on silent for work. Unfortunately, the alerts aren’t as reliable or intuitive as I expected. I’m still trying to work out the kinks, but so far, it hasn’t consistently notified me when I receive calls.Stress Monitoring:I was also interested in the ring’s stress monitoring feature, but the app doesn’t seem to track stress levels accurately—or at all.On the positive side, the ring is sleek and comfortable, and I do appreciate the app’s features for sleep tracking and exercise monitoring. With some improvements, this could be a great all-around fitness ring.
