    I love this purchase. I’ve had it for about 8 months now. It has given me insight to a lot of my body’s critical metrics, and improved my lifecycle. I recently noticed the battery draining quickly, and the support team was able to immediately diagnose the problem and is replacing it for me.

    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.
