Great customer service
I purchased an Oura Gen 3 in June 2024, with the intention of using it alongside Natural Cycles App to track my cycles. For me the activity tracking and sleep was a bonus and not something I thought i'd use, but as time progressed I used the ring to gamify improving my health. The reports generated by Oura are also incredibly insightful and useful to share with healthcare providers as evidence if ever needed. The battery life was good (I'd say at least 4 days). I had no issues with the ring until August 2026, when suddenly the ring went from 83% charge to zero overnight and would no longer charge. I used the app to speak to a virtual adviser, who was able to diagnose the ring and get me in touch with a person via email (i could have spoken to live chat within 3 mins but chose not to) within a few hours to go through next steps. The outcome was that my ring was replaced and upgraded to Gen 4 due to no Gen 3 stock. A sizing kit arrived within a couple of days (another good step in the process as my previous size would have been too big due to sensor size changes), and my ring arrived less than a week after my last ring broke. Brilliant customer service, which is aligned to what one might expect with the premium price and subscription charges.
