My second Oura ring (3rd gen) is ~3 years old and is currently collecting dust in a drawer because the battery lasts < 24 hrs, and If you forget to sync your data by opening the app (which can take a minute or longer of having the app open in the foreground) before it dies, it dumps all data collected since the last sync. Super frustrating.

I might be able to get it replaced if support decides to be generous, but dealing w/support is a pain, and the alternative is buying a $400 replacement every 2-3 years when the battery starts to fail.

I don't have to pay the monthly subscription - they had a deal where you could buy a third gen ring (at full price) and would get lifetime access without paying a monthly subscription. Despite that it still doesn't feel worth it to me to have yet another device I have to babysit (remember to sync with the app every day, remember to wear, remember to charge) and pay hundreds of $ to replace every 2-3 years. With the subscription cost, there's no way this product's value proposition makes sense for me.
