While I still love the ring form factor. As tacky as it sounds, I still wear my bricked Oura rings sometimes just because I like the feel lol. However, I would never trust Oura ((or any other device outside of Apple(unfortunately)) to gauge you health off their data. While Oura is directionally correct (like most of them), it never once detected low oxygen levels in my sleep and I have some of the worst central sleep apnea my doctor has seen.
