    Intended use was for working out and it felt weird lifting things with it. Not only that but calorie tracking wasnt accurate. Sleep trackint was awesome though!

    I got this ring because I was trying to track my cycle to have a baby this year. The ring does not provide exact measurements you must link the data to an outside application, which also costs a monthly premium. The ring scratches VERY easily and battery dies way too often. I'd rather just take my temperature manually and use my apple watch. Would not buy again. Said I was always stressed, which I already knew from my therapist...

    Purchased the Oura Ring for our daughter for Christmas, she absolutely loves it, great data and easy to use. It’s worth it to purchase the latest version, 100%. Best Buy was great to work with.

    Nice stats with it, but the monthly membership was a turn off. Sometimes wasn’t as accurate.

    I absolutely love my Oura ring. The only reason I won’t give it 5 starts is the battery.it was advertised as 8 days but I get 5 if lucky and it’s really frustrating when traveling.
