    This ring is awesome as long as you go into it with proper expectations of what a smart ring was originally designed to do. Definitely get brushed silver, though, because it is the only one that hides scratches well.

    I bought my Oura 4 ring in April 2025. I loved how it tracked my walking and other exercises. However, over the last few months, the ring no longer automatically detects them. What happened? Customer support is by chat and has not been very helpful.
