    I studied this for q year before making my purchase. I must say if you are a health junkie like me and like to keep track of your health markers this ring is for you. The silver tone is gorgeous and I find it does not scratch easily. I still bought a cover for it just to protect it.

    Super product that provides multiple types of information on the health of the wearer. I use mine to track my steps, sleep, and heart rate. Oura tech is great, and frequently adds new types of information. Extremely easy to sync with a phone.
