Helpful
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.His ha been beneficial in tracking several health factors through the day. The only drawback is how tight the ring needs to be to read well, also causes that sweat band/discoloration on your finger.

Happy with purchase!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.So far I’m loving my Oura ring. I wanted it to get some feedback on sleep and other markers of longevity. It takes a few weeks for it to collect data and now I’m starting to get some good feedback! I also love the pink ceramic and have gotten some complements on it!

Best purchase of the year!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Ring really gives really good information on your daily activities. Tracks in real time, alerts you when you're idle gir extended periods of time. Tracks sleeping habits and much more. Really good for people recovering from major surgeries. Ask me how I know... lol. Best purchase I've made this year!
