    The Good:

    + I love my Oura ring. I use it mainly to track my total sleep time, sleep efficiency, resting heart rate, and heart rate variability.

    + It acts as a reminder for me to practice better sleep hygiene and lovingly admonishes me when it catches my late night snacking.

    + I also like using it to judge recovery in the mornings. If my recovery score is bad I will usually not push myself too hard in the gym that day.

    + The app is great and the ring form factor is really convenient and comfortable.

    + Battery life: I am charging my ring about once every 5 days or so. Takes about 1.5 hr to fully charge.

    The BAD:

    - I don't think the sleep stages are that accurate, judging from the limited studies that they have comparing the Oura ring to polysomnography. If I wanted an accurate breakdown of my REM / Deep sleep I would get an EEG based sleep tracked like the Dreem 2.
