Oura Support Vent!
I have had the Oura Ring for about a year. My original ring failed due to a faulty battery and was replaced. 5 months later, and now that replacement has stopped working too. For context, I do not swim, shower, or wash dishes with it on, so this is not a wear and tear issue.
First support experience: The rep quickly identified the battery issue, skipped the runaround, and sent a replacement. Easy and efficient.
Second support experience: I contacted support again and explained upfront that I had already completed all troubleshooting steps, including a factory reset. The rep responded with a list of instructions for exactly what I had just told him I already did. When that went nowhere, his solution was to manually input my data
I paid $500 for a device that automatically tracks sleep, activity, and health metrics. Manually entering data defeats the entire purpose of owning one. Two hardware failures in one year on a $500 device is a problem on its own. Inconsistent support makes it worse. I wish I had listened to the people who said not to buy this. Switching to the Apple Watch and moving on.
TL;DR: $500 ring, two failures in one year, support told me to manually input my data. Avoid.
