Sleep Tracking: My Oura Ring Review (After Two Years)

I got my Oura ring in January. I have insomnia, so a few times a week it is giving me the red warning on restfulness and not enough REM sleep (less often not enough deep sleep).

I'm working on an EEG to get better sleep stats, and then with that data, do real-time sleep interaction/management.

I can't quite put my finger on why I like the ring so much. I don't need it anymore, I know I don't sleep well, having it tell me that isn't helpful. Yet they've done something really well.
