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.

I've had this ring for about 6 months… I've had this ring for about 6 months now. This ring is very comfortable and the readings for fitness and wellness are pretty accurate. I like the fact that the tracking app is free and they're constantly making updates. I charge my ring every 7 days and could probably go 8. I really hope they eventually add more color selection for rings. I'd definitely buy another one.

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

Everything as promised Everything as promised. Received the rings to evaluate the best size. When requested got tracking update. Received the smart ring in given time frame. Only thing missing now is to have the software with more features. But it's going well. Quite happy
