    I decided on the Oura Ring over a smart watch and I am happy with its simplicity. So many options available within the app itself to help monitor your daily health, sleep, and activity.

    So far so good, Sizing I'm still up in the air on. I did sizing in store and was advised to go a size up for finger swelling, but most of the time the ring is pretty floppy on me. The ring has quite a bit of scratching on it and haven't had it very long.
