Sharing this for other buyers
Sharing this for other buyers, especially those outside the US. My Oura Ring 5 developed a battery issue within the first couple of weeks, draining far faster than the advertised 6-9 days — even after turning off Blood Oxygen Sensing and completing two full calibration cycles. Support confirmed it was a hardware defect and processed a replacement. Customer service (Jonah, Member Care) was responsive and professional throughout. Two things international buyers should know: 1. Oura cannot currently ship warranty replacements directly to some countries, including Brazil. I had to arrange an alternate US address through a family member, adding significant delay. 2. Replacements may be refurbished/factory-reset units, not new ones, even when the original had a hardware defect.
