I ordered three rings I ordered three rings. One of the ring size was not accurate. There’s no way to return the ring. I was told that I cannot return the ring because I chose the size. Please note an American seven fits me perfect this particular rain fits on my pinky finger horrible horrible service

I appreciate the app keeping me aware… I appreciate the app keeping me aware of my activities. Hopefully my life improves because of my healthy choices. Slight negative, the charge does not last 7 days.

Trully outstanding ! Trully outstanding ! First one i receive was bornes and They replace it with no stupid question super app on iPhone work super good Fit super well and confortable too wear all day long and i dont Like wear ring. Only complain is The black finish that Wear off rapidly (should take silver)

Great tool to monitor my health I have been able to use the information on the app to understand how things are working with my CPAP. Also, after a recent surgery to see how low my O2 level was during the night after the surgery. I wish you had put a mark on the outside of the right that shows it is positioned correctly for reading. I tried myself, but nothing seems to stay on the coating. If there was a mark on the outside of the ring that would be towards the palm of your hand it would be easy to know that it had not twisted around too far.

Overall this ring is great! Overall this ring is great!! I do wish there was some sort of gauge /alert on the actual ring, when the battery is running low (vs having to check the app) Also more ‘activity’ measuring is a must! That is being worked on (i.e. measuring output of running, aerobic classes, Elliptical, Pilates, Biking….)
