    I had wanted one of these rings since they first came out, and finally bit the bullet and bought this newest version. I’m very pleased with the daily information it provides, which is much more than my iPhone does. If you’re looking for a way to track and improve your health and productivity, I highly recommend the Oura ring 4.

    This ring is awesome in my opinion and very comfortable to where given its thickness. I ferl this ring is far more comprehensive than the other rings out there. The only thing I didn't like was the subscription to get the full feature set. The annual fee isn't bad, its just that there are several other options that don't charge subscriptions.
